Effect of subarachnoid anesthesia combined with propofol target-controlled infusion on blood loss and transfusion for posterior total hip arthroplasty in elderly patients.

Abstract：

BACKGROUND:Intravertebral and general anesthesia (GA) are two main anesthesia approaches but both have defects. This study was aimed to evaluate the effect of subarachnoid anesthesia combined with propofol target-controlled infusion (TCI) on blood loss and transfusion for total hip arthroplasty (THA) in elderly patients in comparison with combined spinal-epidural anesthesia (CSEA) or GA. METHODS:Totally, 240 patients (aged ≥65 years, American Society of Anesthesiologists [ASA] I-III) scheduled for posterior THA were enrolled from September 1st, 2017 to March 1st, 2018. All cases were randomly divided into three groups to receive CSEA (group C, n = 80), GA (group G, n = 80), or subarachnoid anesthesia and propofol TCI (group T, n = 80), respectively. Primary outcomes measured were intra-operative blood loss, autologous and allogeneic blood transfusion, mean arterial pressure at different time points, length of stay in post-anesthesia care unit (PACU), length of hospital stay, and patient satisfaction degree. Furthermore, post-operative pain scores and complications were also observed. The difference of quantitative index between groups were analyzed by one-way analysis of variance, repeated measurement generalized linear model, Student-Newman-Keuls test or rank-sum test, while ratio index was analyzed by Chi-square test or Fisher exact test. RESULTS:Basic characteristics were comparable among the three groups. Intra-operative blood loss in group T (331.53 ± 64.33 mL) and group G (308.03 ± 64.90 mL) were significantly less than group C (455.40 ± 120.48 mL, F = 65.80, P < 0.001). Similarly, the autologous transfusion of group T (130.99 ± 30.36 mL) and group G (124.09 ± 24.34 mL) were also markedly less than group C (178.31 ± 48.68 mL, F = 52.99, P < 0.001). The allogenetic blood transfusion of group C (0 [0, 100.00]) was also significantly larger than group T (0) and group G (0) (Z = 2.47, P = 0.047). Except for the baseline, there were significant differences in mean arterial blood pressures before operation (F = 496.84, P < 0.001), 10-min after the beginning of operation (F = 351.43, P < 0.001), 30-min after the beginning of operation (F = 559.89, P < 0.001), 50-min after the beginning of operation (F = 374.74, P < 0.001), and at the end of operation (F = 26.14, P < 0.001) among the three groups. Length of stay in PACU of group T (9.41 ± 1.19 min) was comparable with group C (8.83 ± 1.26 min), and both were significantly shorter than group G (16.55 ± 3.10 min, F = 352.50, P < 0.001). There were no significant differences among the three groups in terms of length of hospitalization and post-operative visual analog scale scores. Patient satisfaction degree of group T (77/80) was significantly higher than group C (66/80, χ = 7.96, P = 0.004) and G (69/80, χ = 5.01, P = 0.025). One patient complained of post-dural puncture headache and two complained of low back pain in group C, while none in group T. Incidence of post-operative nausea and vomiting in group G (10/80) was significantly higher than group T (3/80, χ = 4.10, P = 0.043) and group C (2/80, χ = 5.76, P = 0.016). No deep vein thrombosis or delayed post-operative functional exercise was detected. CONCLUSIONS:Single subarachnoid anesthesia combined with propofol TCI seems to perform better than CSEA and GA for posterior THA in elderly patients, with less blood loss and peri-operative transfusion, higher patient satisfaction degree and fewer complications.
