고관절 전치환술시 시행된 마취방법에 따른 결과 비교 = Comparison of General and Spinal Anesthesia in Patients Undergoing Primary Unilateral THR

다국어 초록 (Multilingual Abstract)

One hundred twenty eight patients underwent 128 primary unilateral total hip arthroplasties from January 1992 to December 1995. Patients were divided into two groups based on the type of anesthesia utilized for their procedure. Group I consisted of 56 patients (35 women and 21 men; average age 56 years) who had general endotracheal anesthesia. Group II consisted of 72 patients (40 women and 32 men; average age 58 years) who had spinal anesthesia. Data were analyzed by anesthesia group to compare a variety of clinically relevant factors. No statistically significant differences in each groups were noted regarding average age at the time of surgery, the underlying diseases, the number of preexisting medical conditions, surgical time, length of hospitalization, deep venous thrombosis, deep infections, death and intraoperative blood transfusion. Significant differences were observed for two factors: 1) estimated intraoperative blood loss was higher in Group I (p <0.05), and 2) postoperative hemovac output was also greater in Group I (p <0.05). In conclusion, spinal anesthesia appears to be a safer modality for patients, especially with pulmonary problems undergoing primary unilareral total hip replacement.
