The purpose of this prospective, randomized, double-blinded, active-controlled study is:

To assess the effectiveness of systemic administration of lidocaine and esmolol in combination (vs. either drug alone) will result in improved postoperative outcomes for patients undergoing abdominal surgery (e.g., less pain and postoperative constipation, nausea and vomiting, faster return of bowel function, resumption of normal activities of daily living), leading to a shorten length of hospital stay, maintaining hemodynamic stability during general anesthesia, when administered as intravenous adjuvants

Primary Outcome Measures:
  • Post Operative Pain [ Time Frame: 1 month ] [ Designated as safety issue: No ]
    Outcome will have a duration of one month

Secondary Outcome Measures:
  • Opioid consumption obtained from the recorded data [ Time Frame: 1 month ] [ Designated as safety issue: No ]
    Perioperative use of opioid consumption inside hospital (recorded by study staff and data obtained from patient charts) Post discharge use of opioid consumption (data obtained from the follow up questionnaires during the first month after surgery)

  • Postoperative nausea and vomiting using a Verbal Rating Scale [ Time Frame: 1 month ] [ Designated as safety issue: No ]
    Outcomes will be measured with follow up questionnaires during the first month after surgery

  • Return to normal activities of daily living using follow up questionnaires [ Time Frame: 1 month ] [ Designated as safety issue: No ]
    Description: return to normal activities of daily living(including dietary intake, bowel and bladder function, physical activities)

  • Patient satisfaction using a verbal rating scale from 0 to 100 [ Time Frame: 1 month ] [ Designated as safety issue: No ]
    0= Not satisfied 100= Excellent

Detailed Description:

Finding the optimal combination of anesthetic adjuvant drugs for maintaining hemodynamic stability during surgery is a challenge (1-3). Traditionally, potent opioid analgesics like fentanyl and its newer analogs have been used for this purpose. However, use of opioid compounds is associated with well-known side effects (e.g., ventilatory depression, postoperative nausea and vomiting, constipation, ileus, bladder dysfunction, urinary retention, pruritus, drowsiness and sedation). All of these common side effects interfere with the early recovery process and contribute to a delayed resumption of normal activities (4, 5). Increasingly, non-opioid analgesics (e.g. β-blockers and local anesthetics) are being utilized as adjuvant drugs during surgery for treatment of acute hyperdynamic responses (increased catecholamine release) during surgery, as well as, facilitation of the recovery process after surgery because of their anesthetic and analgesic-sparing effects. The β-blocking drugs, esmolol and labetalol have been used as an alternative to short-acting opioid analgesics for controlling the transient, acute autonomic responses during surgery (5-8), They have been shown to reduce the anesthetic requirement during intravenous (propofol) or volatile-based anesthesia (6,7,10-13) and to decrease opioid consumption intraoperatively and in the PACU (8). They may also improve hemodynamic stability during induction and emergence from anesthesia in the perioperative and early postoperative period and facilitate the resumption of normal activities after major surgical procedures. The anesthetic and analgesic-sparing effects of β -blockers also lead to a faster emergence from anesthesia and reduce postoperative opioid side effects (e.g., PONV) (14-18). Perioperative intravenous esmolol has shown improvement in perioperative outcomes, decreases acute hemodynamic responses, reduces anesthetics and opiods use during anesthesia, facilitates a faster emergence from anesthesia, reduces intraoperative and postoperative opioid requirements, reduces side effects as such as pruritus, constipation, ileus, nausea and vomiting (PONV) and thereby shortens the hospital stay. (3, 7, 13, 18)

Local anesthetics like lidocaine possess analgesic, antihyperalgesic and anti-inflammatory properties. Perioperative intravenous lidocaine has shown improvement in perioperative outcomes in patients undergoing abdominal surgery to decrease intraoperative requirement of Inhalants/Intravenous agents, opioid consumption, postoperative pain, fatigue, nausea and vomiting scores, maintain hemodynamic stability, facilitate a more rapid recovery of gastrointestinal function, improve postoperative recovery, fast resumption of normal activities of daily living and shorten length of hospital stay, when administered as an adjuvant during surgery.(19,23-29,33)

Theoretically, it would be extremely beneficial to administer an adjuvant (to patients undergoing abdominal surgery) that is capable of effectively controlling autonomic responses during surgery, while providing a faster recovery with fewer side effects. Preliminary data suggests that the perioperative effects of systemic administration of lidocaine and esmolol is most effective in facilitating bowel recovery, decreasing opioid consumption in the intra/postoperative period, and shorten length of hospital stay with early recovery. Therefore, we designed this prospective, randomized, double-blinded, active-controlled study to test the hypothesis that systemic administration of lidocaine and esmolol in combination (vs. either drug alone) for maintenance of hemodynamic stability during surgery will result in improved postoperative outcomes for patients undergoing abdominal surgery (e.g., less pain and postoperative nausea and vomiting, and faster return of bowel function and resumption of normal activities of daily living); leading to a shorten length of hospital stay.
