Analgesic Efficacy of Lidocaine for Suction-Assisted Lipectomy with Tumescent Technique under General Anesthesia

INTRODUCTION: Bilateral ultrasound-guided peripheral block (TAP - block) in the plane between the inner oblique abdominal muscle and the transversal abdominal muscle – TAP plane, is a regional anesthesia technique by infiltration of a local anesthetic, provides analgesia for operations involving the anterior abdominal wall. The analgesic effectiveness of the block decreases the consumption of opioid analgesics and non-steroidal anti-inflammatory drugs. AIM: In this study, we evaluated the intraoperative analgesic efficacy of bilateral TAP - block and the consumption of opioid analgesics in patients undergoing bilateral laparoscopic inguinal hernia repair. METHODS: The study was conducted with 35 patients, who were randomized into two groups. In the control group (group I), there are patients who received general anesthesia (GA), and experimental group (group II), were patients who have received general anesthesia and a bilateral tap block (GA + TAP). RESULTS: Patients with TAP-block (group II) have significantly lower fentanyl consumption compared to group I. CONCLUSION: Multimodal approach for the simultaneous administration of general anesthesia with a TAP block provides effective intraoperative analgesia and significantly reduces the perioperative consumption of opioid analgesics.

Vertebral lumbar surgery can be performed under both general anesthesia (GA) and spinal anesthesia. A clear benefit from spinal anesthesia (SA) remains unproven. The aim of our meta-analysis was to compare the early analgesic efficacy and recovery after SA and GA in adult patients undergoing vertebral lumbar surgery. A systematic investigation with the following criteria was performed: adult patients undergoing vertebral lumbar surgery (P); single-shot SA (I); GA care with or without wound infiltration (C); analgesic efficacy measured as postoperative pain, intraoperative hypotension, bradycardia, length of surgery, blood loss, postoperative side effects (such as postoperative nausea/vomiting and urinary retention), overall patient and surgeon satisfaction, and length of hospital stay (O); and randomized controlled trials (S). The search was performed in Pubmed, the Cochrane Central Register of Controlled Trials, and Google Scholar up to 1 November 2020. Eleven studies were found upon this search. SA in vertebral lumbar surgery decreases postoperative pain and the analgesic requirement in the post anesthesia care unit. It is associated with a reduced incidence of postoperative nausea and vomiting and a higher patient satisfaction. It has no effect on urinary retention, intraoperative bradycardia, or hypotension. SA should be considered as a viable and efficient anesthetic technique in vertebral lumbar surgery.

Quadratus Lumborum

Background: Ultrasound-guided quadratus lumborum (QL) block, is local anesthetic technique providing perioperative somatic, perhaps even visceral, analgesia for patients of all ages. The aim of this study is to evaluate the analgesic efficacy of ultrasound-guided anterior QL block versus ultrasound-guided caudal block in pediatric patients undergoing hip surgery. Patients and Methods: This prospective, randomized study was carried out on seventy patients aged 1-7 years, of both with ASA physical status I or II scheduled for elective surgical correction of developmental dysplasia of hip (DDH). Anterior QL Block Group: Patients received ipsilateral ultrasound-guided anterior QL block after induction of general anesthesia using of bupivacaine 0.25% (0.5 mL/kg). Caudal Block Group: Patients received ultrasound-guided caudal block after induction of general anesthesia using of bupivacaine 0.25% (0.75 mL/kg). Postoperative pain scores were assessed on admission to PACU and at 1, 2, 4, 6, 8, 12, 18 and 24 h postoperative. Total intraoperative fentanyl (µg) consumption, total postoperative rescue analgesic (morphine) consumption, time to the first rescue analgesic administration and Parent satisfaction were assessed. Heart rate and mean arterial blood pressure had been recorded pre–operative, every 15 min intra-operative , and postoperative on admission to PACU and at 1, 2, 4, 6, 8, 12, 18 and 24 h postoperative. Any undesirable side effects during the first 24 hours such as, bradycardia, hypotension, local hematoma at the side of injection, nausea and vomiting had been recorded. Results: The median FLACC score was significantly lower in anterior QL block group than caudal block group at 4,6,8 and 12h postoperative (P<0.001). Total intraoperative fentanyl (µg) consumption was insignificant different between both groups (P=0.862). Post-operative morphine consumption was significantly lower in anterior QL group compared to caudal group (P<0.001). Time to first postoperative analgesic requirement was significantly prolonged in anterior QL block group compared to caudal block group (P < 0.001). The incidence of nausea and vomiting was insignificantly different between both groups (P > 0.999). Conclusions: Ultrasound-guided anterior QL block provided effective and long lasting postoperative analgesia than ultrasound-guided caudal block with lesser postoperative analgesic consumption in pediatric patients undergoing surgical correction of DDH.

Anesthetic Solution

The tumescent technique of lipo-suction is a modification of the wet technique. A large volume of very dilute epinephrine is infiltrated into a targeted fat compartment prior to lipo-suction, producing a swelling and firmness. This tumescence of fat permits an increased accuracy in lipo-suction and minimizes postsurgical irregularities or rippling of the skin. Epinephrine-induced vasoconstriction minimizes blood loss, bruising, and postoperative soreness. Safe, rapid infiltration of large volumes of solution is achieved using a closed sterile system featuring a newly designed blunt-tipped, 30-cm-long, 4.7-mm-diameter needle having a hollow handle that accommodates a 60-cc syringe. Attached to a liter bottle of anesthetic solution by an intravenous line, the needle is inserted via the same incision and deposits the solution along the same path as that intended for the lipo-suction cannula. Thus, the solution is infiltrated exactly where it is needed for hemostasis or local anesthesia. Used in conjunction with general anesthesia, the tumescent technique saves time in achieving maximal vasoconstriction of the targeted fat compartment. If dilute lidocaine (0.1%) is added to the solution, the technique permits lipo-suction of more than 2 liters of fat totally by local anesthesia. Twenty-six patients, having received a mean lidocaine dose of 1250 mg (18.4 mg/kg or 8.5 mg/kg/hr) infiltrated into subcutaneous fat, had a mean serum lidocaine level of less than 0.36 μg/ml 1 hour after completion of the infiltration.
