title: Retrospective Evaluation of Anaesthesia Techniques for Hip Replacement Operations.
abstract: OBJECTIVE
  In this retrospective study, we evaluated the demographic characteristics of patients that underwent hip replacement surgery in our orthopedic clinic. Associated diseases, preoperative laboratory findings, intraoperative findings, and the effect of admission or refusal to the intensive care unit on postoperative mortality and morbidity were recorded. Furthermore, we tried to identify surgical and anaesthetic methods applied, intraoperative hemodynamic changes, length of stay in the post-anaesthesia care unit, and postoperative complications.
  
  
  METHODS
  Demographic characteristics, co-morbidities, preoperative laboratory findings, intraoperative findings, and admission or refusal to the intensive care unit of patients who underwent hip replacement surgery between January 2008-December 2010 were enrolled.
  
  
  RESULTS
  Out of 500 patients, 33.4% (n=164) were operated under general anaesthesia, 34% (n=170) under combined spinal-epidural anaesthesia, 22.2% (n=111) under spinal anaesthesia, 6.4% (n=32) under combined lomber plexus block and sciatic nerve block, and 4% (n=20) under epidural anaesthesia. Mean hospital stay was 7 days in the general anaesthesia group and 5 days in the regional anaesthesia group.
  
  
  CONCLUSIONS
  American Society of Anesthesiologists (ASA) scores and incidence of co-morbidities were higher in the partial hip replacement group. Admission to the intensive care unit was lower in the total hip replacement group. Hospital stay was shorter in the partial hip replacement group. Mortality rates on the 7(th) and 30(th) days were higher in the partial hip replacement group.
