General or Regional Anesthesia for Hip Surgery
General Versus Intrathecal Anaesthesia for Patients Undergoing Elective Total Hip Arthroplasty
研究概览
详细说明
A randomized controlled trial (RCT) with a follow up time of 48 hrs. Patients scheduled for primary Total Hip Arthroplasty. A total of 120 patients randomly assigned to one of the two alternatives (general anaesthesia (GA) or regional anaesthesia (RA)).
General anaesthesia compared to intrathecal anaesthesia will give shorter length of hospital stay (LOS) for patients undergoing total hip arthroplasty (THA).
Primary endpoint:
LOS.
Secondary endpoints:
Postoperative pain? Postoperative orthostatic function (dizziness) Time until the patient meets the discharge criteria from PACU How many patients will need at least one urinary bladder catheterisation

Post Operative Pain
大体时间:from end of surgey until 48 hrs later
|
Pain will be monitored using a Visual Analogue Scale.
Pain will be monitored with the patient in four different positions.
VAS 100 mm used for assessment of pain (0 = no pain, 100 = worst imaginable pain).
At each time and position the median VAS-pain score was reported (generally the distribution of pain scores are not normally distributed and hence median value was used)
|
from end of surgey until 48 hrs later
