To Observe Haemodynamic Parameters Including, Heart Rate, Blood Pressure, Respiratory Rate , and Oxygen Saturation, With or Without Giving Reversal Agent on Extubation, in Patients Receiving Single Shot of Atracurium , and to Observe Post Operative Residual Paralysis and Airway Reflexes in PACU.

Not Applicable

Completed

• Conditions: Tachycardia; Hypertension; Hypoxia; Hyperventilation; Residual Paralysis, Post Anesthesia
• Interventions: Drug: neostigmine (reversal agent); Drug: Placebo drug ( normal saline )

• Registration Number: NCT07097441
• Lead Sponsor: Ziauddin University

Brief Summary

The goal of this clinical trial is to to observe the haemodynamic parameters including Heart Rate Blood pressure Respiratory rate and Oxygen Saturation with or without giving reversal agent on extubation in patients receiving atracurium on induction , it will also observe post operative residual paralysis respiratory depression and airway reflexes in the post anaesthesia care unit Researchers will compare neostigmine which is the reversal agent and the placebo drug by giving it at the end on surgery before extubation to observe haemodynamic parameters The main questions it aims to answer are Will participants have a stable haemodymaics if no reversal ( neostigmine ) is used during extubation Will it provide a safe extubation and no complications post operatively Participants will be given Either neostigmine or placebo drug at the end of surgery before extubation Will be obseved and monitored for two hours postoperatively in the post anaesthesia care unit Will be monitored for post operative complications like respiratory depression or residual paralysis

.

Detailed Description

Objective : To observe the haemodynamic parameters including Heart Rate Blood pressure Respiratory rate and Oxygen Saturation with or without giving reversal agent on extubation in patients receiving atracurium on induction , and secondary objective was to observe post operative residual paralysis respiratory depression and cough and gag reflex Study design : Controlled , randomised , and triple Blind trial . Place and duration of study: Dr Ziauddin Hospital Clifton Karachi , from March to June 2025.

Methodology : This was a triple blind study . A total of 100 patients were randomly assigned by the CTU to two groups , the placebo group ( Group A ) and the neoglycopyrolate group (Group B) based on computer generated allocation. At the end of the surgery, patients in Group A were administered IV normal saline and Group B were administered neoglycopyrolate 50 mcg/kg . The primary outcome was to observe heart rate , blood pressure, oxygen saturation and respiratory rate after giving the drug , before extubation , at extubation and at 1mins, 5mins, 10mins, 20mins, and 2h thereafter, while the secondary outcome was to observe post operative airway reflexes and residual paralysis in the post anaesthesia care unit

Arm && Interventions

Group	Intervention	Description
Neostigmine group ( Group B )	neostigmine (reversal agent)	This group will reeive neostigmine ( reversal agent ) at the end of surgery before extubation and then haemodynamic parameters will be observed
normal saline group ( Group A )	Placebo drug ( normal saline )	This group will receive normal saline ( no reversal ) at the end of surgery before extubation and then haemodynamic parameters will be observed

Primary Outcome Measures

Name	Time	Method
Heart rate	From the time of extubation till discharge from post anaesthesia care unit	To observe Heart rate, via pulse oximeter and ECG
Blood Pressure	From the time of extubation till discharge from post anaesthesia care unit	to observe Blood Pressure via Sphygmomanometer
Respiratory Rate	From the time of extubation till discharge from post anaesthesia care unit	to observe respiratory rate via capnometer
Oxygen Saturation	From the time of extubation till discharge from post anaesthesia care unit	to observe oxygen saturation via pulse oximeter

Secondary Outcome Measures

Name	Time	Method
Airway reflexes	From the time of extubation till discharge from post anaesthesia care unit	to observe cough and gag reflex via Binary scale e.g Yes/No
Residual paralysis	From the time of extubation till discharge from post anaesthesia care unit	to observe head lift for more than 5 secs and firm hand grip via Bonary scale e.g Yes/No
