Setting: This study was conducted at People's Medical College Hospital, People's University of Medical & Health Sciences for women, Nawabshah, Sindh, Pakistan, from October 2008 to April 2009. Patients and Methods: Patient demographic data include age, sex, weight. The procedural data include type and duration of surgery, onset and duration of motor block, height and duration of sensory block, complications and failure of spinal anesthesia. Spinal performed in lateral decubitus position with 0.75% bupivacaine 0.3 mg/kg. The adequacy of block was judged by motor paralysis in lower limbs and lack of response to firm skin pinch at incision site. Results: 46 cases out of 50 cases were successful, three cases failed due to difficulty in locating subarachnoid space and inadequate flow of CSF, one case failed for no obvious reason. Demographics: 42 patients were male and 8 female, Age range 10 to 82 months; mean 36.75 +/? 19.4. Block characteristics: Onset of motor block 113.2 +/? 6.9 seconds, motor block duration range 75 to 120 minutes, mean 107 +/? 10.8 minutes, Height of analgesia T5.3 +/? 0.89. Hemodynamics. BP & HR remained stable throughout the procedures. Conclusion: Pediatric spinal anesthesia is a safe, reliable and effective technique.
