Postoperative analgesia by femoral nerve block with ropivacaine 0.2% after major knee surgery: Continuous versus patient-controlled techniques☆

Abstract

All 3 strategies provided effective pain relief. PCFA resulted in a lower consumption of ropivacaine (toxic and financial impact). PCFA + Inf does not improve postoperative analgesia.

Ropivacaine in ultrasound-guided femoral nerve block: what is the minimal effective anaesthetic concentration (EC90)?

“…This low concentration has not been used before to provide anaesthesia. Infusion of 0.2% ropivacaine through a femoral catheter is commonly used for postoperative analgesia; however, it is not associated with the dense quadriceps block achieved in this study [8]. This contradiction may be related to the use of different injection devices (needle vs catheter).…”

“…Femoral nerve block is commonly performed, relatively simple, effective and with numerous indications [2][3][4]. Ropivacaine is a long-acting local anaesthetic that is widely used including for femoral nerve block [4][5][6][7][8]. The success rate of a nerve block relies on multiple interacting variables [9][10][11][12][13][14]; increasing the local anaesthetic volume or concentration generally improves block success rate, but at the expense of an increase in the local anaesthetic dose [9][10][11][12][13][14].…”

Controle da dor pós-operatória da artroplastia total do joelho: é necessário associar o bloqueio do nervo isquiático ao bloqueio do nervo femoral?

“…They concluded that the bolus administration consumed 58% less bupivacaine when compared with continual injection associated or not with bolus administration, which produced similar analgesia. Eledjan et al 21 had the same conclusion using the same alternatives. One hundred and thirty-six patients undergoing large surgeries of the knees, including 66 TKA, were studied.…”

A review of the literature on chiropractic and insomnia

“…The topics of these studies were as follows: impact of chronic pain on health care seeking, self care, and medication; rehabilitation of chronic low back pain using continuous epidural analgesia; discomfort, awareness, and recall in the intensive care-still a problem; and postoperative analgesia by femoral nerve block with ropivacaine 0.2% after major knee surgery. [16][17][18][19] Another search was conducted with the selection criteria to include manual therapy. This search did not identify any studies that met the selection criteria.…”
