Opioid-free cesarean section with bilateral quadratus lumborum catheters
Local and Regional Anesthesia Feb 14, 2020
Hernandez N, et al. - Researchers report an instance of narcotic-free pain control using continuous bilateral posterior quadratus lumborum (QL) blockade as the main mode of analgesia in an elective cesarean section delivery (CD). They describe the case of a woman, aged 36 years old, who presented at 37 weeks of gestation in active labor scheduled for elective primary CD. At L4–L5, spinal anesthetic was performed using hyperbaric 0.75% bupivacaine, without intrathecal morphine. They placed bilateral posterior QL catheters under sterile conditions with 20 mL of 0.25% bupivacaine per side. Then, they initiated a continuous infusion of 0.2% ropivacaine at 10 mL/hour per side. QL catheters, as well as a multimodal pain regimen comprising non-steroidal anti-inflammatory drugs and acetaminophen, were used to control patient’s pain. A resting pain score of 0 with a dynamic pain score of 3 out of 10 throughout her recovery was reported by the patient. On day 3 after the operation, the patient was discharged, and the catheters were removed without any complications. Although intrathecal morphine is regarded as the gold standard for pain control after CD, it causes many adverse impacts. A reduced opioid consumption has been confirmed in relation to bilateral single-shot QL blocks after CD but its limited duration has a minimal benefit over intrathecal morphine and patients continue to need oral narcotics for pain relief. Overall, an opioid-free CD for the postoperative period may likely be achieved by using QL catheters and a multimodal pain regimen.
