Background: To maintain a high standard of patient care, it is essential to provide adequate pain management in patients who undergo laparoscopic surgery.
Methods: We randomly enrolled 74 women who underwent laparoscopic surgery for gynecological benign diseases. Patients in the levobupivacaine group (n=37) were injected with 7 ml of 5 mg/ml levobupivacaine at all incisional areas patients in the control group (n=37) were injected with an equal volume of physiologic saline solution. In the postoperative period the following variables were assessed for each group: decline of hemoglobin concentration, consumption of analgesics, time of ambulation, length of postoperative ileus, length of postoperative hospital stay, and VAS scores at 6, 12, and 24 h after surgery.
Results: Mean pain intensity at 6 and 12 h after surgery was significantly lower in the levobupivacaine group than in the control group (p<0.01). Analgesic requirement was significantly lower (p<0.01) in the levobupivacaine group (0.3 phial+/-0.2) than in the control group (2.1 phial+/-1.0). The mean time of ambulation was significantly lower (p<0.05) in the levobupivacaine group (16+/-4) than in the control group (22+/-6). No significant difference was observed between the two groups in mean pain intensity 24 h after surgery, decline of hemoglobin concentration, length of postoperative ileus, or length of postoperative hospital stay.
Conclusions: Our results suggest that presurgical infiltration of levobupivacaine in addition to general anesthesia and standard analgesic therapy significantly decreases the intensity of postsurgical pain, especially for the first 12 h after surgery, and reduces analgesic consumption after surgery.

Comparative Efficacy of Intrathecal Hyperbaric Levobupivacaine With Fentanyl Versus Hyperbaric Bupivacaine With Fentanyl in Elective Cesarean Section.

Article Synopsis
- A study was conducted to compare the effects of hyperbaric levobupivacaine versus hyperbaric bupivacaine, both with fentanyl, in women undergoing elective cesarean sections.
- A total of 130 women participated, with findings showing that levobupivacaine resulted in fewer side effects and shorter sensory and motor block durations than bupivacaine.
- Both anesthetics maintained hemodynamic stability, but levobupivacaine provided effective pain relief for a shorter time, suggesting it as a viable option for cesarean procedures.
The Effect of Dexmedetomidine and Levobupivacaine in an Experimental Ischemia Reperfusion Model.

Background/aim: Although it has been reported that different molecules are effective in preventing ischemia-reperfusion (I/R) injury, the most effective treatment is still unknown.
Materials And Methods: The rats were divided into four groups of eight rats each. Group C: 1 ml intraperitoneal (IP) isotonic + laparotomy + IP 2 ml isotonic +I/R.

This study aimed to compare the analgesic and cardiopulmonary effects of levobupivacaine with or without dexmedetomidine, in cats undergoing ovariohysterectomy. In this prospective, randomized, and blinded clinical trial, 24 healthy cats were recruited. Animals received either saline (S group; 2 mL NaCl), levobupivacaine alone (Lev; 0.

Backgrounds: Ultrasound-guided proximal and distal approaches of the intercostobrachial nerve (ICBN) blocks facilitate analgesia for upper arm and axillary surgery, though success rates vary and lack clinical comparison. This study compared their anesthetic and analgesic efficacy as an adjunct to the supraclavicular brachial plexus block for upper arm arteriovenous access surgery.
Methods: 60 end-stage renal disease patients undergoing upper arm arteriovenous access were randomly assigned to receive either proximal or distal ICBN block using 10 mL of a mixture of levobupivacaine and lidocaine with epinephrine.

Department of Cardiology, Dr. Ram Manohar Lohia Institute of Medical Sciences, Lucknow, Uttar Pradesh, India.
Background And Aims: This study aimed to compare the effects of three local anaesthetic (LA) agents, namely bupivacaine, levobupivacaine, and ropivacaine, on the cardiac conduction system as assessed by corrected QT (QTc) and P wave dispersion (PWD) intervals in lower limb orthopaedic surgeries and to find the most suitable LA agent that can be used for a long duration.
Methods: The study included 75 patients with American Society of Anesthesiologists physical status I and II of either gender in the age group of 18-65 years undergoing elective lower limb orthopaedic surgeries under epidural anaesthesia. These were allocated to groups B (bupivacaine), L (levobupivacaine), and R (ropivacaine).
