Comparative  Evaluation of  Low dose Hyperbaric Bupivacaine with or without Fentanyl in Spinal Anaesthesia for Caesarean Section in patients with Pregnancy Induced Hypertension

BACKGROUND: Occurance of meconium-stained amniotic uid (MSAF) during labour may be considered as a measure for prediction of poor fetal outcomes such as meconium aspiration syndrome and perinatal asphyxia ,resulting in perinatal as well as neonatal morbidity and mortality. It constitutes about 5% of deliveries with meconium stained amniotic uid and death results in about 12% of infants with MAS. METHODS: 40 cases of meconium stained liquor detected after spontaneous or artical rupture of membranes taken during labour from june 2020 to december 2020 and their outcome in terms of mode of delivery(whether vaginal delivery or lower segment caesarean section) and fetal outcome and associated maternal high risk were studied RESULT: Anemia was co existant in around 15%, pregnancy induced hypertension(PIH) in 25%and premature rupture of membrane in 10%.Pregnancies complicated with Pregnancy induced hypertension had signicant higher rate of meconium stained liquor among all cases. Caesarean Section was commonly performed in meconium stained amniotic uid cases and accounted for about 65%of all cases. CONCLUSIONS: Meconium Stained amniotic uid increases the chances of caesarean rates,leading to birth asphyxia ,Meconium Aspiration Syndrome and hence increases the chances of neonatal intensive unit admission.

Background: Spinal anaesthesia induced hypotension, a common problem during caesarean section, is associated with maternal nausea and vomiting and the risk of neonatal acidosis. Low dose local anaesthetic combined with opioids spinal anaesthesia better preserves maternal haemodynamic stability, resulting in equally efficacious anaesthesia.Objectives: To investigate whether this synergistic action could be used to provide effective anaesthesia while preventing hypotension during caesarean operation.Materials and method: This prospective study included 60 pregnant mothers scheduled for caesarean operation who were then divided into two groups (thirty in each). Group-A received a spinal injection of 12.5 mg of standardized 0.5% hyperbaric bupivacaine and group-B received 8 mg of 0.5% hyperbaric bupivacaine with 20 ?gm fentanyl. Hypotension was defined as the systolic blood pressure drops below 90 mm of Hg or a decrease of systolic blood pressure 25% from pre anaesthesia level and hypotension was treated with a bolus of 5 to 10 mg of intravenous ephedrine. The quality of anaesthesia and postoperative analgesia were evaluated.Results: The mean time required to reach peak sensory level was earlier in group-B than group-A and was statistically significant (p<0.05). The decrease in systolic blood pressure in group-A was significantly more than group-B (p<0.05) and vasopressor requirement was also significantly more in group-A compared to group-B (p<0.05). Mean time of two segment regression of sensory analgesia and complete sensory recovery was significantly early in group-B (p<0.05). Duration of motor recovery in group-B was significantly earlier (p<0.05). The duration of effective analgesia was significantly more in group-B (p<0.05).Conclusion: Low dose Bupivacaine with fentanyl provided excellent intraoperative sensory and motor blockade, haemodynamic stability, and effective postoperative analgesia for caesarean delivery.Delta Med Col J.
