AbstractObjective: To compare the effects of different types of anesthesia on postoperative cardiopulmonary complications in patients aged 80 years and above who received unilateral hip fracture surgery. Methods: The perioperative data of patients aged 80 and above who underwent unilateral hip fracture surgery in Peking Union Medical College Hospital from July 2009 to June 2014 were collected and grouped based on the types of anesthesia including general anesthesia, neuraxial anesthesia, and peripheral nerve block. Variables were analyzed including preoperative general conditions (age, sex, type of fracture, ASA physical status classification, preoperative cardiopulmonary complications), intraoperative conditions (type of surgical procedure, operative time, blood loss, total intraoperative fluid infusion), and postoperative conditions (length of hospital stay, postoperative hospital stay, ICU stay, postoperative newly developed cardiopulmonary complications, postoperative in-hospital death, hospitalization costs). The incidences of postoperative cardiopulmonary complications of each group were analyzed and compared. Results: A total of 219 cases were finally analyzed including general anesthesia (n=46), neuraxial anesthesia (n=90) and nerve block group (n=83). Fewer cases with preoperative pulmonary complications were noticed in general anesthesia group (15 cases, 32.6%) than in neuraxial anesthesia group (45 cases, 50%) and nerve block group (47 cases, 56.6%) (χ(2)=6.912, P=0.032). No statistical differences were found between groups regarding preoperative cardiovascular complications and other variables. There were no significant differences in postoperative cardiopulmonary complications. However, the cost of hospitalization was lower in neuraxial anesthesia group (45.6±21.4) thousand RMB and nerve block group (48.2±25.8) thousand RMB compared with general anesthesia group (56.3±21.6) thousand RMB, the difference was statistically significant(F=9.951, P=0.007). Conclusions: For elderly patients undergoing unilateral hip surgery, the type of anesthesia does not affect the incidence of postoperative cardiopulmonary complications. However, neuraxial anesthesia and nerve block may reduce the cost of hospitalization.
