ASYNCHRONOUS INTRATECAL ANAESTHESIA IN SURGICAL TREATMENT OF ANAWAL HERNIA

Abstract

In the main group (n = 20; 39.4 years ± 4.1 years; 71.4 kg ± 4.3 kg, I–II ASA) asynchronous intrathecal anaesthesia (AIA) 10 mg of hyperbaric bupivacaine in combination with 0.06 mg of buprenorphine was administered in patients with inguinal hernia repair. The control group (n = 20; 42.6 years ± 0.9 years; 75.4 kg ± 3.6 kg, I–II ASA) received synchronous intrathecal anaesthesia (SIA) 15 mg with isobaric bupivacaine in combination with 0.06 mg of buprenorphine during similar operation. The AIA and SIA provided effective pain relief for operations with long postoperative analgesia. In the AIA group, a hemodynamics was stable due to the lateral rather than bilateral sympathetic block, in contrast to the CIA. Improving the quality of analgesia allowed an early activation and enteral nutrition of patients, as well as a shortened rehabilitation period. An intrathecal administration of bupivacaine supplemented with buprenorphine was characterized by a significantly smaller number of negative side effects compared with the corresponding administration of other opioids.
