Comparative Study of Low Dose Vs Regular Dose of Bupivacaine in Patients with Pregnancy Induced Hypertension undergoing Caesarean Section under Spinal Anaesthesia

Neuraxial administration of local anesthetics improve the quality of intraoperative analgesia and also provides postoperative pain relief for longer duration. The present study was conducted to study and compare the effects of low dose bupivacaine used intrathecally in parturients with PIH.25 ASA grade II patients with PIH defined as blood pressure between 140-160/ 90-110 mmHg without proteinuria were selected and divided into 2 groups as Group (I) -Low Dose Bupivacaine and Group (II) -Regular Dose Bupivacaine-. Haemodynamic variables like systolic and diastolic blood pressure, heart rate were recorded every 2 minutes upto delivery of baby and then every 5 minutes until end of surgery. We conclude the low dose bupivacaine group does not cause any significant side effects and provides stable haemodynamic conditions without fetal or maternal compromise.
