Surgery - Antibiotic administration in surgical procedures
The tenets of effective antibiotic prescription Over the past 40 years, antibiotic resistance has escalated significantly. The development of new antibiotics is limited, and there is an urgent necessity to preserve the effectiveness of current antibiotics. The UK Department of Health has released a 'Start Smart – then Focus' systematic strategy to guarantee the effective and optimal use of antibiotics.

Commence antibiotics only in the presence of unequivocal evidence of infection. Conduct a comprehensive medication allergy history assessment. Examine regional antibiotic prescribing protocols. Commence early and effective antibiotic therapy within one hour of diagnosis (or as soon as feasible) in patients with severe sepsis or life-threatening illnesses. Refrain from the improper application of broad-spectrum antibiotics• Record the clinical indication (including disease severity), drug name, dosage, and administration route in the drug chart and clinical notes. • Include a review or cessation date, or specify the duration. Acquire cultures before initiating therapy where feasible (but do not postpone therapy). • Administer single-dose antibiotics for surgical prophylaxis in instances where their efficacy has been demonstrated. • Specify the precise indication on the medication chart for clinical prophylaxis instead of referring to long-term prophylaxis.
Subsequently, concentrate on evaluating the clinical diagnosis and the ongoing necessity for antibiotics at 48–72 hours, while establishing a definitive plan of action—the 'antibiotic prescribing decision.' All intravenous antibiotics have should be evaluated at 48 hours.
The five alternatives for 'antibiotic prescribing decisions' are: Discontinue antibiotics in the absence of infection evidence. Transition antibiotics from intravenous to oral administration. Alter antibiotics, preferably to a narrower range, or broader if necessary.Proceed to record the subsequent review and cessation date.
Outpatient parenteral antibiotic therapy (OPAT) involves administering parenteral antibiotics to patients outside of an inpatient environment.
Antibiotic prophylaxis in surgical procedures
Antibiotic prophylaxis is an efficacious measure for mitigating surgical site infections (SSI) in specific surgical procedures.
Numerous additional risk variables also influence the occurrence of SSIs. When prescribing antibiotics for surgical prophylaxis, it is essential to weigh the associated risks against the advantages of treatment.
Factors influencing the incidence of SSIs
Patient Extremes of age
Poor nutritional status
Obesity (>20% of ideal body weight)
Diabetes mellitus (DM)
Smoking
Coexisting infections at other sites
Bacterial colonization (e.g. nasal colonization with
Staphylococcus aureus)
Immunosuppression
Prolonged post- operative stay
Operation
Length of surgical scrub
Skin antisepsis
Preoperative skin preparation
Length of operation
Antibiotic prophylaxis
Operating theatre ventilation
Foreign material in surgical site
Surgical technique
Post- operative hypothermia
Advantages of antibiotic prophylaxis
The efficacy of antibiotic prophylaxis in surgical procedures correlates with the frequency and severity of surgical site infections (SSIs).
Surgical site infections can elevate the likelihood of patient morbidity and prolong hospital stays.
The duration of hospitalization related to SSIs is contingent upon the type of surgery performed on the patient.
Evidence suggests that preventing wound infections correlates with reduced durations of stay and expedited patient recovery.
Risks associated with prophylaxis (and antibiotic usage in general)
Optimizing surgical antibiotic prophylaxis is essential to mitigate the unexpected repercussions of antibiotic utilization.
Significant concerns linked to antibiotic prescribing encompass: penicillin allergy, Clostridium difficile infection (CDI), and antibiotic resistance.
Penicillin allergy—penicillins and cephalosporins are the most frequently utilized kinds of antibiotics. Mislabeling patients as penicillin-allergic can jeopardize their antibiotic treatment.
Obtaining a comprehensive medical history, encompassing the specifics of the patient's reported reactions to penicillins or other antibiotics, is a crucial step in determining the patient's allergy status.
Individuals with a confirmed penicillin allergy should not receive β-lactam antibiotics due to cross-sensitivity with penicillins.
Examples of antibiotics in penicillin allergy
Antibiotics that must be avoided in serious
penicillin allergy
Amoxicillin (e.g. co- amoxiclav/ Augmentin® HeliClear®)
Ampicillin (co- fluampicil/ Magnapen®) Benzylpenicillin/ penicillin G
Flucloxacillin (co- fluampicil/ Magnapen®)
Phenoxymethylpenicillin/ penicillin V
Piperacillin- tazobactam (in Tazocin®)
Pivmecillinam
Ticarcillin (in Timentin®)
Antibiotics to be avoided in serious penicillin
allergy and used with caution in non- severe
penicillin allergy (e.g. minor rash only)
Cephalosporins: cefaclor, cefadroxil, cefalexin, cefixime, cefotaxime, cefpirome, cefpodoxime, cefprozil, cefradine, ceftazidime, ceftriaxone, cefuroxime
Other β-lactam antibiotics: aztreonam, imipenem, meropenem, ertapenem
Antibiotics considered safe in penicillin allergy
Amikacin, ciprofloxacin, clarithromycin, clindamycin, colistin, co- trimoxazole, doxycycline, erythromycin gentamicin, linezolid, metronidazole, nitrofurantoin,
minocycline, rifampicin, sodium fusidate, teicoplanin, tetracycline, tobramycin, trimethoprim, vancomycin
The risk of getting C. difficile infection is elevated in patients who have undergone recent gastrointestinal surgery,had an extended hospitalization. Are administered proton pump inhibitors (PPIs),Are aged individuals. Patients now receiving or who have recently received antibiotics, particularly broad-spectrum antibiotics, are at an increased risk of Clostridioides difficile infection (CDI).
The prevalence of antibiotic resistance is rising worldwide, particularly in healthcare environments. The emergence and proliferation of antibiotic resistance within a population is associated with the population's exposure to antibiotics. Inappropriate and excessive use of antibiotics might result in antibiotic resistance. Not all surgical procedures necessitate antibiotic prophylaxis. The NICE recommendations advise against the routine use of antibiotic prophylaxis for uncomplicated clean non-prosthetic surgeries.
Three Prophylaxis is necessary for the following surgical procedures: Clean surgeries that involve the insertion of a prosthesis or implant. Clean-contaminated surgical procedure. Operative intervention on a contaminated or infected wound necessitates antibiotic therapy, alongside prophylactic measures.
Selecting an antibiotic for prophylaxis
A diverse array of bacteria can induce infections in people. Selecting the suitable antibiotic will depend on patient-specific characteristics, the probable site of infection, and local susceptibility patterns.
Initially, consult your local hospital's antibiotic prescribing guidelines. These policies are formulated by MDTs and are grounded in the most reliable evidence and clinical competence. Timing of antibiotic treatment for surgical prophylaxis The route, dosage, and pharmacokinetic characteristics of antibiotics determine the duration required for an antibiotic to attain effective concentrations in particular human tissues. Administering prophylactic antibiotic dosages either too late or too early can diminish their effectiveness and elevate the risk of surgical site infections (SSIs).
Intravenous prophylactic antibiotics for surgical patients should be administered within 60 minutes prior to skin incision, as near to the time of incision as feasible.Three Vancomycin, when warranted, should be administered by IV infusion commencing 90 minutes before the skin incision.Three In most cases, a solitary preventive dose of antibiotic is adequate—always consult the local policy to ascertain the appropriate amount and frequency of administration.
