Brief Summary

Studies evaluating intraperitoneal local anesthetic instillation for pain relief after laparoscopic procedures have provided conflicting results. This randomized, double-blind study was designed to assess the effects of a novel intraperitoneal local anesthetic administration technique using nebulization on pain relief after laparoscopic cholecystectomy.

Outcome Measures

Primary Outcomes (1)

  • Postoperative Pain

    Postoperative pain was assessed by Visual analgue scale (VAS 0 to 100 points) at rest (static VAS) and after a deep inspiration or cough (dynamic VAS). The proportion of patients with adequate pain control after surgery (dynamic VAS \< 3) will also be assessed.

    48 hours

Secondary Outcomes (4)

  • Morphine consumption (mg)

    Up to 48 hours

  • Time of unassisted walking

    Up to 48 hours

  • Hospital morbidity

    Up to 48 hours

  • Time to hospital discharge

    48 hours

Study Arms (2)

Instillation

ACTIVE COMPARATOR

Instillation of Ropivacaine 100 mg in the abdominal cavity

Drug: Ropivacaine 100 mg

Nebulization

EXPERIMENTAL

Nebulization of Ropivacaine 60 mg in the abdominal cavity

Drug: Ropivacaine 60 mg

Interventions

Nebulization grou received intraperitoneal instillation of saline 20 ml on the gall bladder after induction of pneumoperitoneum but before dissection of gall bladder plus intraperitoneal nebulization of ropivacaine 1% 3 ml (30 mg) the start of gall bladder dissection and again at the end of surgery just before deflation of pneumoperitoneum (total of 60 mg). The first ropivacaine nebulization was performed over 5-6 minutes using the Aeroneb Pro® device through the umbilical port while the other ports were being inserted, while second nebulization was performed before the withdrawal of the ports

Nebulization

Instillation group received intraperitoneal instillation of ropivacaine 0.5%, 20 ml (100 mg) on the gall bladder after induction of pneumoperitoneum but before dissection of gall bladder plus and intraperitoneal nebulization of normal saline 3 ml before the start of gall bladder dissection and again at the end of surgery just before deflation of pneumoperitoneum. The first saline nebulization was performed over 5-6 minutes using the Aeroneb Pro® device through the umbilical port while the other ports were being inserted, while second nebulization was performed before the withdrawal of the ports
