Effect of Opioid-sparing Anesthesia on Quality of Recovery After Emergency Laparotomy
A study testing Lidocaine (drug) and Fentanyl (IV) in people with Emergency Abdominal Surgery and Opioid Sparing Anaesthesia, run by Cairo University at 1 site in Egypt.
Trial summary
Opioids are widely used during anesthesia for pain control, but they cause many side effects-such as nausea, constipation, respiratory depression, dependence, and delayed recovery. They can also worsen low blood pressure in patients with unstable circulation. Read more about this study

About this study
Official title: Comparing Effect of Opioid-sparing Versus Conventional Anesthesia on Quality of Recovery After Emergency Laparotomy: a Randomized Controlled Trial
Opioids are widely used during anesthesia for pain control, but they cause many side effects-such as nausea, constipation, respiratory depression, dependence, and delayed recovery. They can also worsen low blood pressure in patients with unstable circulation. Because of these risks, multimodal analgesia is recommended to reduce opioid use.
Research on other non-opioid options is limited. Systemic lidocaine offers anti-inflammatory and opioid-sparing benefits and improves recovery in elective colorectal surgery, but its role in emergency laparotomy is still unclear and requires further study.
Read the detailed description
preoperatively, 8 mg dexamethasone will be slowly administrated. Fluid responsiveness will be defined as a 10% increase in stroke volume after passive leg raising maneuver. If responder will be given 500-mL bolus of lactated ringer.
induction of anesthesia: 2 mg/kg propofol and 1 mg/kg succinyl choline. Anesthesia will be maintained by isoflurane in air/oxygen admixture. Atracurium will be administered after patient recovery from succinylcholine at a dose of 0.5 mg/Kg.
A 10-12 mL/kg/hr of lactated ringer will be infused during the procedure. If patients developed hypotension (mean arterial pressure (MAP) ≤ 70% of the baseline reading and/or <65 mmHg), a fluid bolus of 4 mL/kg will be given and the change in the pulse pressure will be noted. If the pulse pressure increases by >10 %, the fluid bolus will be given until the increase in pulse pressure is <10%. If hypotension persists despite the adequate volume replacement a 5-10 mg bolus of ephedrine will be given. The bolus will be repeated if MAP was not restored within 2 min. Infusion of norepinephrine can be given if MAP persisted <65 mmHg despite 5 boluses.
At the end of the procedure, all patients will receive 1 gm of paracetamol intravenously and local infiltration of the wound with 40 mL of 0.125% bupivacaine.
Postoperative management All patients will receive 1 gm/ 6h of paracetamol.
- Being tested
- Lidocaine (drug), Fentanyl (IV)
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Lidocaine (drug)Drug
induction bolus of 0.15 mL/kg of 10mg/ml lidocaine, followed by 0.15 mL/kg/h infusion (10 mg/mL lidocaine) until end of procedure
Fentanyl (IV)Drug
induction bolus of 0.15 mL/kg of 10mg/ml fentanyl, followed by 0.15 mL/kg/h infusion (saline) until end of procedure
| Study group | Role | What they receive |
|---|---|---|
| lidocaine group | Active comparator | lidocaine bolus at induction followed by infusion until the end of procedure Receives: Drug: Lidocaine (drug) |
| Fentanyl group | Active comparator | fentanyl bolus at induction followed by saline infusion until the end of procedure Receives: Drug: Fentanyl (IV) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Quality of recovery using QoR-15
The QoR-15 scale is a global measure of postoperative recovery, with a score ranging from 0 (extremely poor QoR) to 150 (excellent QoR)
Measured: 24 hours after surgery
Secondary outcomes (8)
intraoperative fentanyl consumption
mcg/kg
Measured: from time of induction of anesthesia until end of procedure
mean arterial pressure
mmHg
Measured: at baseline preoperatively, every 10 minutes (averaging of each 5 readings) from induction of anesthesia until end of procedure, and 2, 6, 10, 16, 24 hours postoperatively.
heart rate
bpm
Measured: at baseline preoperatively, every 10 minutes (averaging of each 5 readings) from induction of anesthesia until end of procedure, and 2, 6, 10, 16, 24 hours postoperatively.
postoperative opioid consumption
nalbuphine in mg
Measured: from extubation until 24 hours postoperatively
numeric rating scale
rate pain on a scale of 0-10, 0: no pain, 10: worst pain
Measured: 30 minutes, 2-, 6-, 10-, 16-, 24 hours postoperatively
serum lactate
Measured: 30 minutes postoperative
respiratory rate
Measured: 30 minutes postoperative
Oxygen saturation/ fraction of inspired oxygen (SF ratio)
Measured: 30 minutes postoperative
