Background and Aims:Low concentration local anaesthetic improves uteroplacental blood flow in antenatal period and during labour in preeclampsia. We compared neonatal outcome after epidural ropivacaine plus fentanyl with intramuscular tramadol analgesia during labour in high-risk parturients with intrauterine growth restriction of mixed aetiology.Methods:Forty-eight parturients with sonographic evidence of foetal weight <1.5 kg were enrolled in this non-randomized, double-blinded prospective study. The epidural (E) group received 0.15% ropivacaine 10 ml with 30 μg fentanyl incremental bolus followed by 7–15 ml 0.1% ropivacaine with 2 μg/ml fentanyl in continuous infusion titrated until visual analogue scale was three. Tramadol (T) group received intramuscular tramadol 1 mg/kg as bolus as well as maintenance 4–6 hourly. Neonatal outcomes were measured with cord blood base deficit, pH, ionised calcium, sugar and Apgar score after delivery. Maternal satisfaction was also assessed by four point subjective score.Results:Baseline maternal demographics and neonatal birth weight were comparable. Neonatal cord blood pH, base deficit, sugar, and ionised calcium levels were significantly improved in the epidural group in comparison to the tramadol group. Maternal satisfaction (P = 0.0001) regarding labour analgesia in epidural group was expressed as excellent by 48%, good by 52% whereas it was fair in 75% and poor in 25% in the tramadol group. Better haemodynamic and pain scores were reported in the epidural group.Conclusion:Epidural labour analgesia with low concentration local anaesthetic is associated with less neonatal cord blood acidaemia, better sugar and ionised calcium levels. The analgesic efficacy and maternal satisfaction are also better with epidural labour analgesia.

Purpose: To evaluate the effect of prophylactic aqueous suppressants immediately post-Ahmed glaucoma valve (AGV) surgery on the rate of hypertensive phase and success. Methods: Retrospective case–control study of 80 eyes with refractory glaucoma undergoing AGV surgery. Forty eyes in the intervention group (preoperative aqueous suppressants continued postoperatively) and 40 in the control group (all glaucoma drops stopped after surgery and reintroduced as required) were included in this study. Patients were followed for 1 year. Data collected included intraocular pressure (IOP), number of glaucoma medications, and number of eyes requiring further IOP lowering surgery. The frequency of hypertensive phase and 1-year success was compared between the groups. Results: Hypertensive phase occurred in 22.5% of the intervention group compared to 42.5% of the control group; however, this difference was not statistically significant ( P = 0.06). Success at 1 year (IOP ≤21 mmHg but ≥5 mmHg and 20% reduction from baseline without additional surgery) was similar in each group: 77.5% in the intervention group and 62.5% in the control group ( P = 0.22). However, at 1 year, significantly more eyes in the intervention group had an IOP ≤17 mmHg (95% vs. 80%, P = 0.04). The mean time interval to a second IOP lowering procedure was significantly shorter in the control group ( P < 0.005). Conclusions: With prophylactic preoperative aqueous suppressants, more eyes achieved an IOP of ≤17 mmHg. The time interval to repeat the glaucoma procedure was significantly shorter in the control group.
