The purpose of this study was to determine if obese patients have a different sensory regression time from subarachnoid block than non-obese patients using hyperbaric 0.75% bupivacaine. A quasi-experimental design was used. Twenty patients were separated into two groups; one group was classified as obese, and the other group was classified as non-obese. The data consisting of age, height, weight, sex, and surgical procedure were recorded preoperatively. All the patients received hyperbaric 0.75% bupivacaine via subarachnoid puncture. The levels of spinal anesthesia were recorded at the highest level achieved. The injection time was also recorded. When the surgery was completed, the patient was transferred to the recovery room and levels of sensory blockade were checked by pin-prick with an 18-gauge needle every 10 minutes until complete recovery from the spinal anesthesia had been achieved.
The hypothesis, there will be no difference in sensory regression time from SAB with hyperbaric 0.75% bupivacaine between obese and non-obese patients, failed to be rejected. No statistically significant difference, using linear regression analysis, was found in mean regression time between groups (obese versus non-obese).
