Post dural puncture headache after spinal anaesthesia for caesarean section: a comparison of 25G Quincke, 27G Quincke and 27G whitacre spinal needles

To compare the frequency and severity of post dural puncture headache in obstetric patients using 25G Quincke, 27G Quincke and 27G Whitacre spinal needles. Comparative, randomized, double-blind, interventional study. Liaquat University Hospital Hyderabad from October 2005 to December 2006. 480 ASA I-II full term pregnant women, 18 to 45 years of age, scheduled for elective Caesarean section, under spinal anaesthesia, were randomized into three groups: Group I [25G Quincke spinal needle: n=168], Group II [27G Quincke spinal needle: n=160] and Group III [27G Whitacre spinal needle: n=152]. Spinal anaesthesia was performed with 1.5-2.0 ml 0.75% hyperbaric bupivacaine using 25G Quincke spinal needle [Group I], 27G Quincke spinal needle [Group II] and 27G Whitacre spinal needle [Group III] at L3-4 inter-vertebral space. Each patient was assessed daily for four consecutive days following Caesarean section. Frequency and severity and of postdural puncture headache [PDPH] were recorded. Data were analyzed using SPSS-11. Frequency of PDPH following the use of 25G Quincke [Group I], 27G Quincke [Group II] and 27G Whitacre [Group III] spinal needles was 8.3% [14/168], 3.8% [6/160] and 2.0% [3/152] respectively. In Group I, PDPH was mild in 5 patients, moderate in 7 patients and severe in 2 patients. In Group II, it was mild in 2, moderate in 3 and severe in 1 patient. In group III, it was mild in 2 and moderate in 1 patient. Severe PDPH did not occur in Group III. Most of the patients with PDPH developed it on first and second postoperative day. When using a 27G Whitacre spinal needle, the frequency and severity of PDPH was significantly lower than when a 25G Quincke or 27G Quincke needle was used

Perinatal mortality and related obstetric risk factors at a tertiary care hospital of Hyderabad

Objective: To determine perinatal mortality rate and its related obstetric risk factors in our setup. Design: Observational study. Setting: Department of Obstetrics and Gynaecology [Unit-I], Liaquat University Hospital Hyderabad, from January to December 2006

Patients and Methods: All perinatal deaths including stillbirths [SBs] and early neonatal deaths [ENNDs] within 0-7 days of birth after 24 weeks of gestation were studied during the study period, while Pregnancies <24 weeks of gestation were excluded from the study. The relevant information was collected through a pre-designed proforma which contained variables including maternal demographics, obstetric risk factors and other details

Results: A total number of 2224 deliveries were analysed for perinatal mortality. Out of these, there were 224 perinatal deaths giving a PNMR of 100.7/1000 births. There were 196 SBs and 28 ENNDs. Among these, 88% women were unbooked. Commonest risk factors was antepartum haemorrhage [27.67%], followed by hypertensive disorders of pregnancy [23.21%] and mechanical factors affecting labour [14.28%]. Congenital abnormalities were found in 9.8% of PNDs while maternal medical disorders were seen in 6.25% cases. In 3.5% cases, chorioamnionitis/ neonatal septicaemia was the underlying cause and multiple pregnancies were seen in only 02 [0.89%] cases. However, in 32 [14.28%] cases, no cause was found

Conclusion: The high perinatal mortality rate in present study is comparable to the figures from other institutions. Main reason being lack of antenatal and pre-pregnancy care where from almost all obstetric risk factors can be picked up and treated / prevented
