Surgery - Operative procedures during gestation
Pregnancy testing: Urinary dipstick for β-human chorionic gonadotrophin (HCG) exhibits a sensitivity of 91%, which is notably lower for women conducting self-tests. Specificity varies from 61% to 100% when assessed from the initial day of the first missed menstrual cycle, which occurs two weeks post-ovulation. Blood β-HCG exhibits nearly 100% sensitivity and specificity, capable of detecting pregnancy 6 to 8 days post-ovulation. False negatives and positives primarily result from user error. Alterations in anatomical and physiological structures Pregnancy induces several alterations pertinent to surgical procedures.
First trimester: Drugs may have teratogenic effects Decreased lower oesophageal sphincter (LOS) tone elevates the risk of gastro-oesophageal reflux and aspiration in the supine position.
Second trimester: • Pharmacological agents may adversely impact fetal growth or metabolism without resulting in overt malformations. • Increased vulnerability to urinary tract infections (UTIs), especially ascending kidney infections and pyelonephritis. The risk of venous thromboembolism (VTE) increases throughout the second trimester and is consistently elevated in the third trimester. • Increased susceptibility to superficial infections.
Third trimester: Drugs may initiate labor. Superior and posterior displacement of the movable abdominal viscera due to the expanding uterus. The appendix is positioned higher in the right upper quadrant (RUQ).
• The risk of hypotension in the supine position arises from inferior vena cava compression by the gravid uterus; this can be mitigated by placing the drugged or unconscious patient in a mild lateral decubitus position. Potential risks of miscarriage The risk of miscarriage associated with surgical pathology and surgery fluctuates by trimester. It is at its peak in the initial instance. The likelihood of viable premature labor increases during the third trimester. The risk of miscarriage associated with GA is consistently weighed against the danger of sepsis resulting from untreated surgical conditions, especially acute appendicitis. This is a prevalent problem in surgical practice. Ultrasound imaging may be ineffective due to inadequate visualization, and CT scanning is contraindicated because of radiation exposure. MRI is frequently utilized post-first trimester. Diagnostic laparoscopy is contraindicated because of the impact of pneumoperitoneum on pregnancy. The sole method for obtaining a diagnosis may necessitate surgery when significant differential diagnoses have been ruled out.
Common differential diagnoses of appendicitis during pregnancy include ectopic pregnancy problems. Pyelonephritis. Imminent miscarriage/placental abruption.
Pharmaceutical prescription during gestation
Screening pharmaceuticals for detrimental effects on the human embryo is unequivocally immoral; hence, numerous novel and frequently utilized medications have not been administered during pregnancy. Certain older medications have been utilized during pregnancy and are considered 'safe' due to the lack of data indicating fetal harm. An essential equilibrium must be preserved between addressing the mother's significant sickness and mitigating any danger to the fetus. In general, refrain from providing medications whenever feasible. Be aware of the pregnant stage; numerous medications are sanctioned only during specific trimesters. Two Verify any medication you prescribe in the BNF (or its equivalent). • If uncertain, see a professional for guidance. • Significant teratogens comprise: • Thalidomide (an antiemetic). • Carbamazepine with sodium valproate. • Isotretinoin. Tetracycline. • Warfarin. • Angiotensin-converting enzyme (ACE) inhibitors. Lithium. • Methotrexate, cyclophosphamide
