Surgery - Assessment of the skin and subcutaneous tissue
Evaluation and characterization of a mass
Significant elements in the historical narrative encompass the following:
• Velocity of development. Accelerated growth in size raises suspicion of cancer (primary or secondary).
• Recent alteration in dimensions. Indicates potential malignant transformation or infection in a once benign tumor.
• Related symptoms. Paraesthesiae or weakness indicates nerve involvement; diminished mobility shows muscle involvement.
• Historical account of regional trauma. May suggest a reason, although a previously undetected underlying mass should always be considered
.Take into account the subsequent factors when assessing a lump.
Fundamental information
Location, Dimensions. And Form.
Characteristics of infection or inflammation:
Elevated temperature, 'calor'.
Tenderness, 'pain'.
Color, 'rubor'.
Characteristics of malignancy
• Surface (e.g. irregular),Irregular edge and Uniformity (e.g. firmness).
Characteristics of fluid or vascular lesions
Fluctuance and/or transilluminance (fluid-filled). Existence of a thrill (fluid-filled, associated with the vascular system). Pulsatile (arterial) ± expansile (suggestive of an arterial aneurysm).
Audible thrill (arterial lesion). Compressibility (e.g., venous lesion or arteriovenous malformation).
Characteristics of locoregional invasion include tethering to adjacent structures. Engagement of adjacent structures (e.g. nerves). Localized lymph node enlargement.
Evaluation and characterization of an ulcer
Significant elements in the historical narrative encompass the following: Is it painful? Diabetic and neuropathic ulcers frequently lack sensation.
Did it originate as an ulcer or did a lump become ulcerated? indicates a cancer of the skin
Describe the basic morphology of the ulcer
Location.
• over pressure points and bony prominences suggests pressure sore.
• medial shin suggests venous ulcer.
Lateral shin, dorsum of foot, and toes suggest arterial ulcer.
Edge.
Sloping edge suggests a conventional ulcer (many aetiologies).
Rolled edge is typical of basal cell (BCC) or squamous carcinomas.
Everted edge suggests squamous or metastatic carcinomas.
Vertical edge (punched out) suggests arterial ulcer or chronic
infection.
Base.
Friable, red, and bleeding suggest venous or traumatic.
Slough suggests infection.
Black hard eschar suggests chronic ischaemia.
Discharge. May suggest an underlying cause, e.g. intestinal fistula with
enteric content.
Surrounding tissue. Erythema and swelling suggest 2° infection.

Surgery - Assessment of the abdominal region
Placement Position the patient supine with sufficient head support (e.g., one pillow) to facilitate relaxation of the abdominal muscles. Arms should be positioned at the sides to facilitate relaxation of the lateral abdominal muscles. Position the patient upright to evaluate the groin if a groin hernia is suspected; however, the majority of hernias and groin pathologies can be examined while supine. Examination
• Overall presentation of the patient. Is there evidence of jaundice or indications of anemia? Does the patient appear malnourished or cachectic?
• Initially, instruct the patient to cough and elevate their head during the examination; this may disclose hernias—observe during both normal and deep breaths.
• general abdomen Is it symmetrical? Is there evidence of global distension, such as ascites or enlarged bowel? Is there evidence of localized distortion (e.g., a localized mass or organomegaly)? Does the abdomen exhibit symmetrical movement during deep respiration, or is this movement diminished in the presence of peritoneal irritation? Is there any coloring indicative of retroperitoneal hemorrhage or significant inflammation, such as periumbilical bruising (Cullen’s sign) or flank bruising (Grey Turner’s sign)?
• Hernia . Where are they located? What is their apparent age? Is there indication of herniation upon coughing? • Is a stoma present? Which category? Does it appear healthy or abnormal? What is the composition of the stoma appliance?
• umbilicusIs it a herniation? Is there any discharge or ulceration indicative of infection or a malignant lesion? Pulsation. Is there observable pulsation? Peristalsis. Is peristalsis observable? (This observation may require many minutes.) Palpation and percussion Adopt a systematic approach. Utilize the palm of one hand (often the right). It is customary to assess and delineate the abdomen in regions. It can be categorized into nine regions or five 'quadrants' ( Initially inspect the areas gently in a predetermined sequence. Detect any lumps or regions of soreness. Conduct the examination with enhanced palpation depth. Return to any discovered masses and attempt to determine their essential characteristics
. • Indicators of peritoneal irritation (localized or widespread). Are there indications of visceral peritoneal irritation (tenderness upon palpation)?
Are there indications of parietal peritoneal irritation, such as guarding, rebound pain, percussion discomfort, or, if pronounced, rigidity?
Masses- Evaluate their surface, edges, uniformity, respiratory movement, and general mobility. • organs. Liver. Palpate from the right lower quadrant (RLQ) to the right upper quadrant (RUQ). Evaluate the edge and any discernible surface—are they smooth, nodular, or rugged? Spleen. Palpate from the right lower quadrant (RLQ) to the left upper quadrant (LUQ), as one would for the liver. • Renal organs. Perform bimanual palpation in each flank.
• Percussion to evaluate the presence of gas or fluid. Gasoline. Is hyperresonance generalized or localized? Is there evidence of diminished dullness across the liver, indicative of significant free intraperitoneal gas?
Fluid (ascites) is characterized by 'changing dullness'—dullness in the flanks that shifts medially when the patient is in a lateral position.
Auscultation-To thoroughly evaluate bowel noises, one must listen for a minimum of one minute. Bowel sounds can be categorized as nonexistent, normal, active, or obstructive, the latter being characterized by high-pitched, frequent sounds, often exhibiting crescendos of activity, such as 'tinkling' or 'bouncing stones.' Rectal examination and external genitalia assessment
Abdominal assessment in most people should encompass a rectal examination; however, in children, this procedure is seldom beneficial and should generally be eschewed. In males, it is essential to assess the external genitalia to rule it out as a differential diagnosis.

Surgery - Assessment of pelvic pathology
Positioning and examination
The examination is conducted in a maximum of three positions: supine (for transabdominal palpation of the 'false' pelvis); supine with hips flexed and abducted (for vaginal and bimanual palpation, which may assist in evaluating rectal pathology); and left lateral position with hips flexed (for rectal palpation and rigid endoscopy). Any personal examination should always be conducted with a chaperone present, especially during pelvic examinations.
• Examination of the perineum. Is the anus malformed? Is there evidence of mucosal or rectal prolapse present? Is the vaginal introitus appearing normal? Is there vaginal prolapse or indications of a cystocele? Are there any scars from prior surgeries, indications of sinus issues, or signs of sepsis? Examine for supplementary or atypical tissue. Are there skin tags, external hemorrhoids, warts, or atypical skin regions, such as anal intraepithelial neoplasia (AIN)? Is an exterior punctum, as observed in a fistula, or the outer boundary of a fissure discernible? Palpation Palpate the inferior abdominal quadrants.
Digital rectal examination
Is the anal tone normal and is the sphincter symmetrical? Is the prostate of normal size with an intact central sulcus? Is the rectal mucosa exhibiting normal characteristics? Is there any lump or pain anterior to the upper rectum (Douglas pouch)? The aforementioned conditions may result from sigmoid disease, small bowel located in the pelvis, a pelvic appendix, or ovarian disease.
• Vaginal examination is frequently excluded unless there is a definitive indication that it may yield significant information. Is the cervix intact and functioning normally? Is the vagina of standard caliber and texture? Is there tenderness in either vaginal fornix? Inquiries Rigid proctoscopy (also known as anoscopy) is conducted in outpatient settings without the need of sedation. Visualizes the inferior rectum and anal canal, facilitating the evaluation of hemorrhoids. It may be supplemented with therapeutic interventions such as banding, injection, or cryotherapy. Rigid sigmoidoscopy, more accurately referred to as 'proctoscopy'
• Conducted procedures on outpatients without the need of anesthesia.
• Seeks to see the rectum up to the recto-sigmoid junction. The sigmoid colon is not sufficiently visualized with this. Results may be suboptimal if conducted without enema preparation.
Transabdominal/transvaginal ultrasonography
• Simple and secure; eliminates radiation exposure.
• Effective for the diagnosis of ovarian pathology (e.g., in right iliac fossa pain). Endoanal/transrectal ultrasound: A 360° scanning endoanal/endorectal probe performed without anesthesia. Endoanal examinations for evaluating anal sphincter integrity. Transrectal imaging for the evaluation of certain rectal tumors, prostate conditions (including biopsy), and presacral abnormalities.
CT imaging
• Preferred diagnostic approach for unexplained pelvic complaints and postoperative complications.
Magnetic Resonance Imaging
Typically conducted with a normal body scanner with external coils, although it may occasionally be executed with an endorectal coil.
• Preferred diagnostic modality for evaluating advanced rectal, gynecological, and urological malignancies, as well as intricate pelvic and anal infections.
The true pelvis is situated between the pelvic inlet, defined by the sacral promontory, iliopectineal lines, and symphysis pubis, and the outlet, delineated by the coccyx, ischial tuberosities, and pubic arch. The 'false pelvis' is situated superior to the pelvic inlet and can be palpated during abdominal examination. The pelvic floor muscles, including the levator ani, are essential for the support and functionality of the anorectum, vagina, and bladder. They receive innervation from the anterior primary rami of S2, S3, and S4. • The anterior relations of the rectum (palpable during a PR examination) are (from inferior to superior): • Women: vagina, cervix, pouch of Douglas. • Men: prostate, seminal vesicles, recto-vesical pouch.

Surgery -Assessment of Breast Pathology
The fundamental principle of breast evaluation is Triple Assessment: This includes a physical examination, subsequent radiological imaging, and biopsy (either fine needle or core biopsy).
Clinical assessment
Placement and examination
Breasts are optimally assessed in a semi-recumbent position followed by an upright position. Initially, the arms are positioned at the sides in a semi-recumbent posture. Subsequently, they ought to be examined in an upright position, with hands placed on the hips (first in a relaxed state and subsequently applying forceful pressure on the hips to engage the pectoral muscles), and ultimately abducted gradually above the head.
Inspection is essential and should focus on the following aspects.
• comprehensive symmetry and placement. Are the breasts of identical size? Is there a deformity resulting from an underlying disease? Is the position standard? • Dermal appearance. Is the skin erythematous or edematous? Is there a fixed form of lymphoedema in the skin known as 'peau d’orange'? Are there any scars from prior surgery?
• Dermal adhesion. Is the skin mobile when the arms are elevated? Tethering indicates the presence of underlying intraparenchymal scarring or a tumor.
Nipples. Are the nipples retracted, displaced, or ulcerated (indicative of retroareolar tumor or infection)? Is there any excretion?
Palpation
For palpation, the hands should be repositioned to the hips, and the patient may recline in a semi-recumbent position once again. Employ the flat surfaces of all four fingers simultaneously. Initially palpate the 'normal' breast. Be systematic and avoid 'kneading' the breast. A typical sequence is: upper outer quadrant; lower outer quadrant; lower inner quadrant; higher inner quadrant; center (retroareolar) region; supraclavicular fossa; and axillary region. Essential characteristics to consider comprise:
• Tangible mass. Is it hard, uneven, and fixed (cancer) or smooth, spherical, and movable (cysts or fibroadenoma)? Diffuse nodularity. Characteristic of a benign condition. Discharge from the nipple upon probing of the central region. Blood indicates a tumor; pus indicates an infection; serous or milky fluid may be inconsequential.
• Axillary and supraclavicular lymphadenopathy. Is it multifocal and attached (cancer)? Ultrasound Imaging
• Simple to execute and devoid of discomfort— often conducted at a breast outpatient clinic. Avoids radiation exposure in young women.
• Extremely adept in distinguishing between solid tumors and cysts. Mammography is utilized for both population screening and diagnostic evaluation. Very unpleasant for the majority of women and entails a minimal radiation exposure.
• Capable of detecting imperceptible lesions
. • Capable of recognizing premalignant lesions, such as ductal carcinoma in situ (DCIS). Mammographic characteristics indicative of malignancy encompass spiculated microcalcifications, irregularities, and stellate outlines.
Biopsy Aspiration cytology
• Well-tolerated, facile to execute, and rapid to report—typically conducted within half a day at the breast outpatient clinic. • Lacks histological data; offers solely cellular information and depends on cellular atypia for malignancy diagnosis. • Fails to distinguish between invasive and in situ cancer. • Occasionally therapeutic for cysts. High sensitivity and specificity.
Guided core biopsy
• Conducted under ultrasound or mammographic supervision utilizing a Trucut® needle or comparable instrument. Can be performed under general anesthesia or local anesthesia. Delivers precise histological data—facilitates cancer grading. Capable of distinguishing between invasive cancer and carcinoma in situ. Extremely delicate and specific.
Alternative (less frequently utilized)
Computed tomography (CT) scanning is beneficial for evaluating significant local invasion and for regional and systemic staging.
CT positron emission tomography (PET) imaging
Valuable for examining ambiguous lesions and detecting unrecognized metastatic illness.
Magnetic Resonance Imaging (MRI) scanning
Periodically employed for diagnostic purposes, such as in women with breast implants.
Essential topics—breast anatomy
The breast consists of epithelial ductal tissue, epithelial secretory lobules, adipose tissue, and connective tissue. It is segmented into four quadrants and a peri- / retroareolar central zone for the clinical characterization of anomalies. The arterial supply originates from segmental perforators of the internal thoracic artery (ITA). Lymphatic drainage is crucial in the therapy of breast cancer.
• Non-pathological lymphatic drainage predominantly occurs to the axillary nodes.
• The medial half may occasionally drain to the internal mammary nodes. Axillary lymph nodes are categorized into three levels: Level 1 is located inferior to the pectoralis minor, Level 2 is situated posterior to it, and Level 3 is positioned superior to the pectoralis minor.

Surgery - Assessment of the neck region
Placement and examination
Position the patient upright at rest, ensuring the head is oriented straight ahead. Examine the neck from the anterior, lateral, and, if required, posterior perspectives.
• examine the neck in a stationary position and while swallowing (a glass of water). Inspect rotation to the left and right if required.
• Examine the neck while instructing the patient to protrude the tongue. Examination (criteria for assessment) Overall symmetry and nodules. Are there discernible lumps? Are they singular or plural? Is the mass positioned in or around the midline? Does the lump exhibit mobility when swallowing, indicating a potential thyroid-related lesion?
• Dermatological irregularities. Are there any ulcers or sinuses indicative of a chronic infection, such as tuberculosis?
• Related structures. Is there evidence of venous distension or observable collateral vessels? Examination by touch Adopt a systematic approach; palpate the cervical areas sequentially. Utilize both hands with the flat of the fingers to assess each side, but manipulate only one hand at a time to avoid 'cross-palpation.' A standard palpation sequence is: anterior triangle (bottom to top); submental region; submandibular region; posterior triangle (top to bottom); supraclavicular fossae; and parotid, preauricular, and postauricular regions. Repalpate the neck as the patient swallows a mouthful of water, focusing on the anterior triangle. Finally palpate the carotid arteries particularly.
• Mass. Is it singular or plural? Multiple strongly indicates lymphadenopathy. Is it precisely located along the midline, potentially associated with the thyroid? Does it exhibit movement during swallowing, typically indicating a thyroid-related issue? What are the overarching characteristics? Thyroid nodule. Is it one-sided or two-sided? Does it exhibit movement with tongue protrusion? Carotid arteries. Are they normal, ectatic, or aneurysmal? Supraclavicular fossae. Is there accompanying lymphadenopathy indicative of malignancy? Auscultation Auscultate the carotid arteries and any significant masses for bruits, indicating hypervascularity or stenosis.
Inquiries Ultrasonography
• Simple to execute and devoid of pain. Avoids exposure to radiation dosage.
• Extremely adept in distinguishing between solid tumors and cysts
Aspirational cytology
Simple to execute and rapid to document.
• Generally widely accepted in outpatient settings. Offers solely cellular information and depends on cellular atypia for the diagnosis of cancer. Does not furnish histology information.
• intermittently beneficial for cysts. High sensitivity and specificity. Contraindicated in cases of suspected vascular lesions. CT scanning is beneficial for evaluating substantial local invasion and for regional and systemic staging of tumors.
• Facilitates the assessment of the thorax in some thyroid neoplasms. CT PET scanning is occasionally employed to evaluate ambiguous lesions detected on standard CT and to find unanticipated metastatic illness. MRI scanning is beneficial for the comprehensive evaluation of local tumor invasion.

Surgery - Abdominal Investigations
Fecal occult blood testing may be chemical or immunological/quantitative—specifically, the quantitative fecal immunochemical test (qFIT). The primary application is as the initial community test for colorectal carcinoma, as outlined in the National Bowel Cancer Screening Programme.
Flexible sigmoidoscopy
• Minimal risk (perforation <1 in 10,000), typically conducted without sedation. • should visualize up to the descending colon. facilitates small therapeutic interventions (polypectomy, biopsy, injection). commonly employed for: diagnosis and evaluation of colitis colonic neoplasia, investigation anorectal hemorrhage.< />pan>
Colonoscopy: Low risk (perforation 1 in 1000); conducted with or without intravenous sedation or Entonox®; necessitates bowel preparation.
• The entire colon should be visualized in over 95% of cases. Permits minimal therapeutic interventions—polypectomy, including endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), injection, tattoo marking, and biopsy. Applicable when comprehensive colonic evaluation is warranted or when colonic and/or terminal ileal pathology is suspected.
Transabdominal ultrasonography
Simple, secure, non-invasive, and eliminates radiation exposure. Common applications encompass: • 1° examination of the biliary tree for gallstones, bile duct dimensions, and liver parenchymal characteristics. • Detection of ovarian pathology, for instance, in cases of suspected appendicitis. Evaluation of the hepatic and splenic parenchyma. Detection of free fluid in abdominal trauma.
Computed Tomography scanning
• Simple and non-invasive; necessitates considerable radiation exposure and intravenous/oral contrast.
• Common applications encompass:

Standard abdominal radiograph
• may detect intestinal blockage, urinary tract calculi, free intra-abdominal air, and intra-abdominal fluid.
The Barium/Gastrografin® enema can be performed as either a single contrast, where contrast material fills the colon to detect strictures and blockages, or a double contrast, which involves a dilute contrast and air to cover the mucosal surface of the colon, however the latter is currently hardly utilized.
Computed Tomography Colonography • Necessitates comprehensive bowel preparation and rectal catheter placement; entails considerable radiation exposure with intravenous or oral contrast.
• Generally employed as an alternative to colonoscopy when it is contraindicated or unfeasible, such as in cases of advanced age, frailty, known strictures, or unsuccessful colonoscopy attempts. Studies on intestinal transit
• Serial abdominal X-rays (AXR) are utilized to monitor the progression of ingested radio-opaque markers.
• They are employed to evaluate intestinal motility and transit duration. PET scanning involves the injection of a radioactive metabolic substrate to identify metabolically active tissues, such as malignancies or areas of inflammation/infection. It is combined with high-resolution CT scanning to accurately locate 'hot spots.' Commonly employed to detect unrecognized metastatic tumor deposits or to distinguish fibrosis from remaining tumor following surgery.
Physiological assessment

Surgery - Assessment of peripheral vascular disease
Placement and examination The patient ought to be assessed in a heated setting while at rest. Ensure to assess the pulse and blood pressure, inspect the belly for aneurysms and scars, and conduct a comprehensive cardiovascular examination, including all peripheral pulses, heart sounds, and carotid auscultation.
Examine the leg in the supine position, subsequently elevated (passively), and ultimately in a dependent position. Fully expose the leg, encompassing the foot or hand, to facilitate a comprehensive examination and eliminate any bandages. The patient should be assessed in an upright position for venous disease. During supine examination,
observe the following:
Appearance Are there any regions with confirmed skin necrosis (dry gangrene, such as the tips of fingers or toes, interdigital spaces, or the heel of the foot)? Are there alterations in chronic venous stasis (such as varicosities, venous dermatitis, lipodermatosclerosis, or leg ulcers)?
Color - Waxy white indicates critical or acute ischaemia; blue and mottled coloration denotes potentially irreversible acute ischaemia; dark red or purple signifies chronic ischaemia.
Color alterations occur with positional modifications. Observe the angle at which the skin of the limb becomes pale when lifted passively (Buerger’s test). Normal extremities may have no blanching whatsoever. An angle of 15° or less indicates significant ischaemia. Observe the occurrence and latency of color change when the limb is in a dependent position. Ischaemic limbs gradually assume a vivid scarlet hue (reactive hyperaemia).
Ulcers-What is the site (digital or pedal) indicative of arterial disease? Ensure to examine the areas between the toes and fingers, as well as the plantar surface of the foot, particularly in cases of diabetes.
• Examination of venous structures. Assist the patient in standing upright. Examine for varicose veins. Are they located within the long saphenous or short saphenous distribution?
Palpation
• Temperature. Is the skin seen as chilly or warm? Is there a transitional phase? Compression and filling of skin capillaries. The standard is 2 seconds or fewer. A delay over 5 seconds indicates markedly diminished perfusion.
• Peripheral pulsations. Commence with the most proximal (major) vessels and go distally. Document whether the pulse is normal (++), diminished (+), or missing (–). Document any discernible excitement.
• In venous pathology, assessments of venous competence may be conducted (% Varicose veins). Surgical grafts. Examine the pathway of any surgical grafts and document the existence or nonexistence of pulses. Auscultation Assess for bruits. Are there bruits in the proximal vessels indicative of stenosis?
Inquiries Handheld Doppler (at the bedside), followed by Duplex ultrasound or CT angiography, are the primary modalities for examining vascular disease.
Portable Doppler ultrasonography • A simple and portable "bedside" assessment for preliminary evaluation. • used to: • Verify the existence of flow within a vessel or graft. • Assess the ankle-brachial pressure index (ABPI). Assess the existence of venous reflux.
Duplex Ultrasound (USS) • Integrates two-dimensional (2D) ultrasound imaging with Doppler-derived flow, shown in color and superimposed in real time. • Arterial duplex: utilized for the evaluation of stenoses and occlusions. Venous duplex: utilized for evaluating reflux or thrombosis in deep and superficial veins.
Computed Tomography Angiography Requires a multi-slice rapid acquisition ('helical'/'spiral') scanner. Images obtained during the arterial and/or venous phase following intravenous contrast administration.
Three-dimensional (3D) reconstruction facilitates the generation of 'virtual angiogram' images. This process is rapid, non-invasive, and comparatively safe. Utilizes iodinated contrast, which is nephrotoxic (relatively contraindicated in renal impairment) and poses a minor risk of allergic reaction. The presence of vessel wall calcification may hinder the visibility of the lumen.
Digital subtraction angiography (DSA) involves X-ray imaging subsequent to the injection of contrast material into the target vessel, effectively eliminating background structures (such as bone) to render the vessel lumen in black. This technique is primarily employed when endovascular intervention is necessary during the same procedure or when prior investigations yield inconclusive results. It is an invasive procedure that necessitates arterial puncture, which carries inherent risks, including the potential for false aneurysm or retroperitoneal hemorrhage associated with groin puncture. • Necessitates iodinated contrast, necessitating vigilance in cases of renal impairment and allergies.
Magnetic resonance angiography produces images of the arterial network by detecting arterial flow throughout the scanning process. • Safe and non-invasive: does not necessitate iodinated contrast, typically employing gadolinium to accentuate circulating blood. • Often overestimates the extent of stenosis due to the underrepresentation of very low flow.

Surgery – Post Operative Nausea and Vomiting
One challenging and unpleasant side effect of anesthesia and surgery that can lengthen recovery is post-operative nausea and vomiting (PONV). The type of operation and case mix have an impact on the incidence of PONV. According to estimates, the incidence of PONV without prophylaxis is 30% when General Anesthesia is used with inhalational medicines. In addition to being a side effect of post-operative opioids, PONV is also caused by patient-specific variables, especially a history of PONV
Apfel PONV prediction system
Opioids used after surgery (1 point)
Gender - female (1 point) ♀
Non-smoker (1 point)
Motion sickness/PONV history (1 point)
The baseline risk of PONV can be decreased using a number of effective treatments. Among these are:
Steer clear of nitrous oxide (N2O)
avoiding anesthetics that are volatile
reduction of opioids used during and after surgery
Drink enough water.
Ondansetron, unless contraindicated, is one of two antiemetics with distinct mechanisms of action that should be administered to patients at risk for PONV. Usually administered orally (PO)
Preoperative antiemetics can also be administered intravenously. Ondansetron 8–16 mg PO is one preoperative antiemetic that can be administered as a single dosage. Prochlorperazine 3–6 mg buccal or 5 mg tablets PO; Cyclizine 50 mg PO. With the exception of dexamethasone, which is administered at induction.
Intraoperative antiemetics can be administered intravenously (IV) at the conclusion of the procedure: • Dexamethasone 3.3–6.6 mg IV (at induction). • 4 mg of ondansetron. Cyclizine (20–50 mg). • 625–1250 micrograms of droperidol.
Post-operative antiemetics: routinely evaluate patients to identify PONV.
Regular intravenous antiemetics should be administered to individuals who are vomiting.
Only mild to moderate nausea can be treated with oral and buccal antiemetics, such as ondansetron 4 mg 6 hours per day, cyclizine 50 mg 8 hours per day, and buccal pro-chlorperazine 12 hours per day.
