| Popis: | BACKGROUND: Epidural anaesthesia is suitable as a sole agent for lower abdominal surgery and surgery on lower limbs. It has some definite advantages over spinal anaesthesia like avoidance of post spinal headache, minimal chances of meningitis, and minimal chances of nausea and vomiting in postoperative period. But administration of conventional dosage of local epidural anaesthetics (15ml and above) for surgical anaesthesia frequently results in multiple hemodynamic changes, including decreases in chronotropism, inotro pism, dromotropism, systemic vascular resistance, cardiac output, and myocardial oxygen consumption. The segmental epidural block denotes the use of a small volume enough to block only the segments involved in the field of surgery. AIM: To study the effect iveness of segmental epidural anaesthesia for inguinal hernia repair. DESIGN: R andomized control study. METHODS: 100 pts belonging to ASA PS I & II posted for inguinal hernia repair given 5ml of 0.5% bupivacaine through epidural route at L1 - L2 level and a fter conforming the adequacy and level of analgesia, the surgery was commenced. If the patient complained of pain during needle prick, then injected local anaesthetic (0.5% Bupivacaine) with an incremental dosage of 1ml at a time, till the complete onset o f analgesia Pulse Rate and Blood Pressure were recorded at an interval of 1 minute for first 5 minutes and then every 5 minutes till the end of the surgery. Oxygen saturation and ECG monitoring was done continuously. Onset of analgesia, level of analgesia ( P re & post operatively), duration of analgesia, total dosage of local anaesthetic used were recorded. Complications like bradycardia, hypotension, respiratory depression, shivering, nausea and vomiting, sweating and inadvertent dural puncture were recorde d. RESULTS: 53% of patients had excellent quality of analgesia and relaxation. 34% patients had good quality analgesia and relaxation, mild discomfort while handling sac. 10% of patients had fair quality of analgesia and relaxation only. In 3% patients the epidural block failed, in whom general anaesthesia was given. Overall success rate was 97%. Intraoperative and post - operative complications were very minimal. No cases of hypotension, bradycardia, nausea vomiting, total spinal block and respiratory depres sion were seen. CONCLUSION: From the present study it can be inferred that 0.5% Bupivacaine 5 - 6 ml is effective for segmental epidural block for inguinal hernia repair. Segmental epidural block is safe anaesthesia with minimal physiological alterations. Wi th less side effects |
