Patient-controlled femoral nerve analgesia versus patient-controlled intravenous analgesia for postoperative analgesia after trochanteric fracture repair

Efficacy of supplemental peripheral nerve blockade for hip fracture surgery: multiple treatment comparison

“…Overall, 1 (5%) RCT 15 was assessed as low risk of bias, 9 (43%) 14,[16][17][18][19][20][21][22][23] had high risk of bias, and the remaining 11 (52%) 13,[24][25][26][27][28][29][30][31][32][33] The Table lists key characteristics of the eligible studies. They were published from 1991 to 2010 and ranged in size from 14-209 participants.…”

“…We were able to compare acute pain intensity between seven nerve block strategies using data from 16 studies comprising 1,089 subjects. In 15 studies, pain was measured on a 10-cm visual analogue scale or an 11-point numeric rating scale, 13,16,17,[20][21][22][23][24][25]27,28,[30][31][32][33] and in one study, a four-point verbal rating scale was used. 18 Pain was also measured at a variety of intervals (ranging from hourly to daily).…”
