AbstractA prospective and randomized study was conducted on 50 full term parturients undergoing labour analgesia at Panna Dai Hospital, R.N.T. Medical College, Udaipur. The parturients were allocated in two groups: group BF (n = 25) received an epidural injection of bupivacaine (0.15%; 15 mg) + Fentanyl (0.0002%); 2 microg/ml); group BEF (n = 25) bupivacaine (0.15%; 15 mg) + Fentanyl (0.0002%; 2microg/ml) + Epinephrine (1.7 microg/ml; 1:600,000). Subsequent top up (same as bolus) was administered at VAS > or = 3. Comparison between the two groups showed no significant difference in onset of analgesia, number of top up doses, degree of motor block and parturients acceptance. The difference in duration of analgesia with addition of epinephrine (93.00 +/- 29.00 min : BEF group; V/S 86.00 +/- 27.00 Min : BF group) did not show any statistical significance between the two groups. Ambulation was achieved in 100% of parturients from both study groups. The incidence of spontaneous delivery was 92% in each group. Parturients in group BEF demonstrated a higher incidence of side effects like nausea and vomiting (4% v/s 0%); hypotension (4% v/s 0%); paresis (8% v/s 0%) and retention of urine (12% v/s 8%) as compared to BF group. To conclude, the addition of epidural epinephrine (1:600,000) to bupivacaine and fentanyl does not affect the duration or quantity of labour analgesia.
