Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The proposed research in this application will investigate postoperative cognitive function, pain index, inflammatory response, and oxidative stress effects of propofol versus sevoflurane anesthetic drugs in patients undergoing elective, non-cardiac abdominal operations under general anesthesia to investigate which of them will significantly maintain better cognitive function, decrease the pain index, inflammatory reaction, and oxidative stress, improve outcome, shorten the postoperative recovery time and reduce length of hospital stay, and consequently the cost of hospital stay.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

1. Ethical committee approval will be obtained from Ethics committee of Faculty of Pharmacy, Damanhour University.
2. Ethical committee approval will be obtained from Ethics committee of General Organization for Teaching Hospitals and Institutes.
3. About 44 patients who are candidate for elective, non-cardiac abdominal surgery under general anesthesia with either propofol infusion or sevoflurane inhalation, will be recruited from Damanhour Teaching Hospital, General Organization for Teaching Hospitals and Institutes.
4. All participants should agree to take part in this clinical study and will provide informed consent.
5. Demographic data; age (year), sex (female/male), weight (kg), height (cm), BMI (kg/m2) will be collected.
6. ASA physical status will be recorded.
7. Venous blood samples (5 ml will be collected by a sterile syringe then placed in a suitable sterile tube to be centrifuged, the serum will be reserved and stored at -80°C until the analysis) before, and 1 hour after operation for evaluating cognitive function by analyses of Neuron Specific Enolase (NSE, µg/L) and (S100-β protein, pg/mL) and for determining inflammatory response by measuring Matrix Metallo-Proteinase-9 (MMP-9, ng/mL), and effect of these anesthetic drugs on oxidative stress by measuring Super Oxide Dismutase (SOD, U/L).
8. Cognitive function scale: Mini-Mental State Examination (MMSE scale, if decreased more than 2 points from before operation indicate that the cognitive function of patients are declined) and pain index: Numerical Pain Rating scale (NPRS) (a scale from 0-10, where 0 = no pain and 10 = maximum worst pain) will be performed on all patients before, 1 hour, and 24 hours after operation.
9. Heart rate (beat/min), oxygen saturation (%), and non-invasive blood pressure (mmHg) (systolic, diastolic, mean) will be recorded before and after operation.

10 Anesthesia duration (min) (the time from induction of anesthesia till stoppage of anesthesia) and operative duration (min) (the time from skin incision till skin closure) will be recorded.

11\. Time to emerge from anesthesia (min) (the time from stopping the use of anesthetics to patients relatively clearly answering the doctor's questions) will be recorded.

12\. The incidence of any perioperative adverse effects will be recorded as; tachycardia, bradycardia, hypertension, hypotension, nausea, vomiting, hypoxia, and bleeding.

* Study design: This is a prospective, randomized (1:1), clinical trial, will be carried out on 44 patients who are candidate for elective, major, non-cardiac operations under general anesthesia.
* Patients will be randomly allocated into two equal groups (22 patients each); group (P) for propofol and group (S) for sevoflurane.
* The day before the operation, patients will be taught to measure postoperative pain based on the NPRS. Patients will be fasting for 6-8 h for a solid meal and 2 hours for clear fluid before the operation.
* On arrival to the operating room, a peripheral IV cannula will be secured and standard monitoring using an electrocardiogram, pulse oximetry, and non-invasive blood pressure will be applied.
* After preoxygenation with 100% oxygen for 3 min, general anesthesia will be induced using IV propofol (2 mg/kg) and IV fentanyl (1 μg/kg), and IV atracurium (0.5 mg/kg) will be given to facilitate tracheal intubation.
* Lungs will be ventilated using volume-controlled ventilation and the tidal volume and ventilation rate will be adjusted to maintain end-tidal carbon dioxide at 35-45 mmHg.
* Anesthesia will be maintained with either total intravenous anesthesia (TIVA) with propofol 6 mg/kg/h in group P or sevoflurane 1.0-1.5 minimum alveolar concentration (MAC) in group S.
* Continuous infusion of IV atracurium (0.3 mg/kg/h), and IV fentanyl (0.5 ug/kg/h) till the end of surgery.
* Thirty minutes before the end of the surgery all patients will be given IV paracetamol (15 mg/kg) for postoperative pain management.
* At the end of the surgery, either TIVA pump or the inhalational anesthetic vaporizer will be turned off and the muscle relaxant will be reversed by giving IV neostigmine (0.04 mg/kg) plus IV atropine (0.02 mg/kg).
* The patient will be extubated and transferred to the post-anesthesia care unit.
* All data and study outcomes will be recorded by a researcher who is blinded to group assignment.
* The primary outcome is the measure postoperative cognitive function by NSE.
