Effect of Lidocaine and Esmolol Alone or in Combination to Improve the Quality of Recovery, Maintaining Hemodynamic Stability During Abdominal Surgery

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

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 opioids 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.
