    Abstract:
    OBJECTIVE: To compare the frequency of postdural puncture headache (PDPH) and failure rate of spinal anesthesia using 25-gauge Quincke and 25-gauge Whitacre needles in obstetric patients. DESIGN: Single blinded, interventional experimental study. PLACE AND DURATION OF STUDY: This study was conducted at the Department of Anesthesiology, Pain Management and Surgical Intensive Care Unit, Dow University of Health Sciences and Civil Hospital, Karachi from November 1, 2003-April 15, 2004. PATIENTS AND METHODS: One hundred females, aged 18-35 years, ASA physical status I and II, with singleton pregnancy undergoing elective or emergency cesarean section under spinal anesthesia were randomly allocated to receive spinal anesthesia either by using 25-gauge Quincke or 25-gauge Whitacre needles. Patients were followed for 3 days postoperatively. Headache, its relation with posture, onset, duration, severity and response to the treatment were recorded. RESULTS: Compared with the Whitacre group, frequency of postdural puncture headache was significantly higher in Quincke group (*p=0.015), while the overall occurrence of non-postdural puncture headache (NPDPH) did not differ significantly between two groups (p=0.736). Most of PDPH developed on 2nd postoperative day, were mild in nature and resolved within 48 hours of their onset. There was no significant difference in the failure rate of spinal anesthesia in both groups (p=0.149). CONCLUSION: It is suggested that use of 25-gauge Whitacre needle reduces the frequency of PDPH without increasing the failure rate of spinal anesthesia in obstetric patients.
