RESUMO
Background: The ultrasound guided transversus abdominis plane (TAP) block which provides effective analgesia after lower abdominal surgeries including caesarean section. It is a simple and reliable technique. In this prospective, randomized double-blind study, we determined the efficacy of TAP block using 0.25% Bupivacaine and 0.9N Saline with respect to VAS for pain, postoperative Tramadol consumption and post-operative ondansetron usage.Methods: This study was conducted on 100 adult patients of ASA physical status I and II in the age group of 18 to 40 years undergoing elective lower segment cesarean section under spinal anaesthesia. Study group received TAP block with 0.25% Bupivacaine and control group received 10 ml of 0.9N saline on each side. Patients were analyzed for postoperative pain by pain score (at rest, on movement, on cough) using VAS was recorded at 0, ½, 1, 2, 4, 6, 12 and 24 hours postoperatively. Need for rescue analgesia was assessed by time to first dose of Tramadol requirement and total dose of Tramadol over 24 hours of postoperative period. Ondansetron (4 mg i.v.) was administered whenever nausea score was more than 2 or the patient vomited. All the data was noted using uniform performs.Results: Patients received TAP block with 0.25% Bupivacaine had better pain scores at first hour of postoperative period during rest, cough and movement which was statistically significant (p<0.0010) in comparison to group B. There was a statistically significant difference (p <0.001) in the requirement of total dose of Tramadol as a rescue analgesia in patients who received transversus abdominis block with 0.25% Bupivacaine (138.77 mg) in comparison with other group(240 mg).The mean time to first request for Tramadol was significantly longer in group A (5.8 hrs) in comparison to group B (1.93 hrs) with p value <0.001. Patients received TAP block with 0.9N saline needed more dose of Ondansetron, however, the difference was not statistically significant (p >0.001).Conclusions: TAP block using ultrasound provides substantial reduction in Tramadol consumption, time to first dose of rescue tramadol when compared with control group. This study reinforces the recommendation for TAP as a part of multimodal post-operative analgesic regimen.
RESUMO
Anterior spinal artery syndrome (ASAS) is a rare and permanent damage, caused as a neurological complication of spinal anesthesia. In this case study, we have given account of our experience of anesthetic management of a documented case of ASAS, posted for inguinal hernioplasty. We did a thorough pre-anesthetic evaluation and found that patient had paraplegia and confi ned to bed with aspiration pneumonitis. He is a known hypertensive and on control with tablet amlodipine 5 mg/day. He was subjected to antibiotic therapy, mucolytics with respiratory physiotherapy and incentive spirometry. After preparing the patient thoroughly, patient was subjected to general anesthesia. Post-operative analgesia was provided with injection fentanyl, given with a syringe pump. Post-operative period was uneventful.
