| Popis: | Introduction/Objective. Spinal anesthesia is often used for hip endoprosthesis surgery. Significant surgical stress response consisting of hormonal, metabolic and inflammatory changes can be initiated by the hip replacement surgery. Intrathecal opioids, as adjuvants to local anesthetics, make spinal block sufficient even with lower doses of the local anesthetics, and the incidence of the side effects reduce to minimum. Methods. This study included 162 patients of either sex, American Society of Anesthesiology classification (ASA) 1?2, scheduled for total hip arthroplasty. The patients had spinal anesthesia with 10 mg of 0.5% bupivacaine with 20 ?g (Group I), or 25 ?g (Group II) or 30 ?g fentanyl intrathecally (Group III). Results. Mean time to achieve maximum motor and sensory blockade was with no significant difference among the groups. Time of motor block duration was shorter in the Group III. Four hours after the operation, patients in the Group I had significantly higher cortisol serum levels. Blood glucose levels were with no significant difference among the groups. Levels of CRP increased remarkably postoperatively in the Group I. Incidence of hypotension, bradycardia, nausea and vomiting was significantly higher in the Group III. Pruritus and shevering were not recorded among the groups. The first time an analgetic was needed postoperatively was the longest in the Group III. Conclusion. The dose of 10 mg of bupivacaine combined with 25 ?g fentanyl was the optimal option to achieve hemodynamic stability, sufficient sensory and motor blockade, and reduce the stress response and incidence of the opioids side effects such as vomiting, nausea, pruritus etc. |
