Local anesthetic

OBJECTIVES: We aimed to investigate whether the timing of administration, using a combination of incisional and intraperitoneal levobupivacaine (0.25%), has an effect on the postoperative pain after laparoscopic cholecystectomy in a prospective, randomized, and controlled study. METHODS: Sixty six patients were allocated to one of the three groups. Group BS received levobupivacaine before trocar site incision and intraperitoneal levobupivacaine immediately after pneumoperitoneum...

BACKGROUND: Although laparoscopic surgeries are associated with reduced surgical stress response and shortened post-operative recovery, intense pain and high analgesia requirements in the immediate post-operative period are often the chief complaints. AIM: The aim of this study was to evaluate the effect of pre-emptive intraperitoneal local anaesthetic drugs on post-operative pain management and metabolic stress response in laparoscopic appendicectomy. METHOD: The method used was a randomized double-blinded placebo-controlled study...

BACKGROUND: This study aimed to determine the effect of local anesthesia administered before laparoscopic surgery (preemptive anesthesia) on postoperative pain. METHODS: The authors searched Medline, EMBase, and the Cochrane Central Register of Controlled Trials, as well as reference lists of textbooks and relevant articles. They contacted experts in the field of anesthesia and laparoscopic surgery for randomized controlled trials comparing preemptive administration of local anesthesia at the incision site or intraperitoneally with postoperative anesthesia administration or placebo...

BACKGROUND: A clinical trial was designed to assess the use of preincisional and intraperitoneal ropivacaine, combined or not with normal saline, to reduce pain after laparoscopic cholecystectomy (LC). METHODS: For this trial, 120 patients were randomly assigned to six groups. For all the patients, preincisional local infiltration of ropivacaine around the trocar wounds was performed. Group A had infusion of ropivacaine at the beginning of the LC. Group B had infusion of ropivacaine at the beginning of the LC plus normal saline infusion at the end...

BACKGROUND: There is controversy about the effectiveness of intraperitoneal local anaesthesia (LA) in laparoscopic surgery. The aim of the present randomized clinical trial was to compare the analgesic effect of pre-emptive (preoperative) versus postoperative intraperitoneal LA in two different types of laparoscopic surgery. METHODS: Between July 2004 and January 2005, 133 consecutive patients scheduled to undergo laparoscopic fundoplication or hernia repair were randomly assigned to one of three treatments: placebo solution (50 ml 0...

In pain control after laparoscopic cholecystectomy, subhepatic administration of bupivacaine immediately after the creation of pneumoperitoneum has been shown to be more effective than administration before the withdrawal of the trocars. We aimed to investigate the effect of intraperitoneal bupivacaine administration to the subhepatic area before the creation of the pneumoperitoneum. Eighty patients undergoing elective laparoscopic cholecystectomy under general anesthesia were included in a prospective, randomized study...

Intraperitoneal administration of local anesthesia is often used to improve pain relief after laparoscopic cholecystectomy. We have conducted a meta-analysis to establish the efficacy of this technique in reducing early postoperative abdominal pain. A systematic literature search revealed 24 randomized, controlled trials assessing intraperitoneal local anesthetic use in laparoscopic cholecystectomy that met inclusion criteria. Of these, 16 studies reported sufficient data to allow pooled quantitative analysis...

BACKGROUND: This study aimed to evaluate the optimal timing of preemptive analgesia with bupivacaine peritoneal instillation in a prospective, randomized, double-blind, placebo-controlled trial. METHODS: In this study, 120 patients qualified for laparoscopic cholecystectomy were randomized to four groups. Group A received 2 mg/kg of bupivacaine in 200 ml of normal saline before creation of pneumoperitoneum. Group B received 2 mg/kg of bupivacaine in 200 ml of normal saline after creation of pneumoperitoneum...

BACKGROUND: The aim of this study was to test the use of preincisional and intraperitoneal levobupivacaine (L-B) 0.25% in laparoscopic cholecystectomies for postoperative analgesia. METHODS: A total of 108 patients under general anesthesia were randomly assigned to receive preincisional local infiltration of 20 ml solution and intraperitoneal instillation of another 20 ml solution. Group A received for local infiltration and intraperitoneal instillation normal saline (NS)...

BACKGROUND: Postoperative pain is less intense after laparoscopic surgery than after open surgery. However, patients may gain additional benefit from a preincisional local infiltration of anesthetic. The aim of this study was to compare the analgesic efficacy of two local anesthetics, ropivacaine and levobupivacaine, for tissue infiltration as a means of improving postoperative pain control after laparoscopic cholecystectomy. METHODS: Using a randomized, double-blind study design, 57 American Society of Anesthesiologists (ASA) I and II patients scheduled for laparoscopic cholecystectomy were randomly assigned to receive local infiltration with 0...

BACKGROUND: Local anesthesia at the trocar site in laparoscopic cholecystectomy is expected to decrease postoperative pain and hence expedite recovery. The aims of this prospective randomized study were to investigate the effect of local anesthesia and to discover whether it is cost effective. METHODS: For this study, 100 patients undergoing laparoscopic cholecystectomy were randomized into two groups. The 43 study patients were injected with 0.5% bupivacaine hydrochloride at the trocar site before the trocars were inserted...

PURPOSE: To examine the combined preemptive effects of somatovisceral blockade during laparoscopic cholecystectomy (LC). METHODS: One hundred fifty-seven patients under general anesthesia receiving local infiltration and/or topical peritoneal local anesthesia were studied. Patients were randomized to receive a total of 150 mg (0.25% 60 mL) bupivacaine via periportal (20 mL) and intraperitoneal (40 mL with 1:200,000 epinephrine) administration of each. Group A received preoperative periportal bupivacaine before incision and intraperitoneal bupivacaine immediately after the pneumoperitoneum...

BACKGROUND: In the context of the much-heralded advantages of laparoscopic surgery, it can be easy to overlook postlaparoscopy pain as a serious problem, yet as many as 80% of patients will require opioid analgesia. It generally is accepted that pain after laparoscopy is multifactorial, and the surgeon is in a unique position to influence many of the putative causes by relatively minor changes in technique. METHODS: This article reviews the relevant literature concerning the topic of pain after laparoscopy...

BACKGROUND: A controversy exists over the effectiveness and clinical value of preemptive analgesia. Additional studies are needed to define the optimum intensity, duration, and timing of analgesia relative to incision and surgery. METHODS: One hundred twenty patients undergoing laparoscopic cholecystectomy under general anesthesia plus topical peritoneal local anesthetic or saline were studied. Local anesthetic (0.5% bupivacaine with epinephrine) or placebo solutions were given as follows: immediately after the creation of a pneumoperitoneum (blocking before surgery), and at the end of the operation (blocking after surgery)...
