OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2015;3(8):2 BMC Anesthesiol. 2014 Nov 5;14:9970 elderly patients with ASA physical status III or IV and scheduled for elective hip replacement were included in this trial. The purpose of this study was to compare continuous spinal anesthesia with combined psoas compartment-sciatic nerve block with respect to hemodynamic effects in elderly high-risk patients. The results from this trial indicated comparable results, with continuous spinal anesthesia taking significantly shorter time to perform than combined psoas compartment-sciatic nerve block.

لماذا كانت هناك حاجة لهذه الدراسة الآن؟
Hip replacements are common in the elderly population. There has been increased interest towards using regional anaesthesia in this patient population, avoiding certain comorbidity-related complications with general anaesthesia that are especially seen in older patients. Two methods of regional anaesthesia that have piqued interest among surgeons are continuous spinal anaesthesia (CSA) and combined psoas compartment-sciatic nerve block (PCSNB). While neither are free of potential complications, its has been suggested that PCSNB may be more advantageous in elderly patients when considering hemodynamic effects. This trial aimed to compare the effectiveness of each anesthesia in elderly patients undergoing hip replacement surgery.
ما هو سؤال البحث الرئيسي؟
In high-risk, elderly patients undergoing hip replacement, how do the hemodynamic effects and anesthesia quality of continuous spinal anesthesia compare with combined psoas compartment-sciatic nerve block?
- Mean arterial blood pressure was significantly higher in the PCSNB group than the CSA group at the beginning of surgery (p=0.038), at the 5th (p=0.029), 10th (p=0.012), and 20th (p=0.009) minutes of surgery.
- 13 patients in the CSA group and 4 patients in the PCSNB group experienced arterial hypotension requiring epinephrine treatment (p=0.012).
- The duration of the block procedure was significantly shorter in the CSA group compared with the PCSNB group (18.51 +/- 1.82 min vs. 35.53 +/- 5.51 min; p<0.001).
- Patients in the CSA group loss significantly less intraoperative blood than patients in the PCSNB group (283.14 +/- 68.66 mL vs. 329.57 +/- 53.66 mL; p=0.02).
- There was a significantly lesser amount of patients in the CSA group that required postoperative rescue analgesic than in the PCSNB group (11 vs. 30; p=0.0001).
ما الذي يجب أن أتذكره أكثر؟
Psoas compartment-sciatic nerve block took longer time to perform, resulted in more intraoperative blood loss, and required more postoperative analgesia, but maintained mean arterial pressure in the first 20 minutes of surgery when compared with continuous spinal anesthesia. Fewer patients in the psoas compartment-sciatic nerve block group experienced arterial hypertension requiring ephedrine treatment compared to the continuous spinal anesthesia group.
كيف سيؤثر ذلك على رعاية مرضاي؟
This study is one of the first investigations into the comparative effect on hemodynamic effects between a combined psoas compartment-sciatic nerve block and continuous spinal anaesthesia in high-risk elderly patients undergoing hip replacement. Based on the findings of this trial, a combined psoas compartment-sciatic nerve block may have less of an effect on hemodynamics than continuous spinal anaesthesia, though appears more technically demanding as evidenced by the increased length of administration. Important to note is the small number of patients included within this study, necessitating the need for further evaluation of PCSNB and CSA in a larger cohort of patients.
