Clinical Trial Summary

To study the effect of lignocaine nebulization on attenuation of the pressor response during induction and emergence of anesthesia in patients with severe pre-eclampsia

Description:

The pressor response to laryngoscopy and tracheal intubation is a very important issue in hypertensive pregnant patients that can lead to increased maternal intracranial pressure, cerebral haemorrhage, and cardiac failure with pulmonary oedema and may result in maternal mortality. The catecholamine release associated with laryngoscopy and intubation also causes uteroplacental vasoconstriction and adversely affect the neonate well-being.

Therefore, the precise control of stress is necessary during general anesthesia in pre-eclamptic patients.Various drugs are used to suppress the pressor response including opioids, lidocaine, along with α and β adrenergic blockers.

in this study the investigators will evaluate the effect of lignocaine nebulization on attenuation of the pressor response.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Systolic, diastolic, mean arterial blood pressure		Preoperative-Intraoperative
Primary	Heart rate		Preoperative-Intraoperative
Primary	Peripheral oxygen saturation		Preoperative-Intraoperative
Primary	Cough score during emergence	Grade of coughing (grade 0: no cough; grade 1: single cough with mild severity; grade 2: cough lasting less than 5 seconds with moderate severity; grade 3: more than 5 seconds of persistent cough)	Up to one hour after extubation
Secondary	APGAR score	APGAR stands for "Appearance, Pulse, Grimace, Activity, and Respiration."; In the test, five things are used to check a baby's health. Each is scored on a scale of 0 to 2, with 2 being the best score	One, 5 and 10 minutes after delivery of the fetus
Secondary	Sore throat and hoarseness of voice	The incidences and severities of postoperative sore throat and hoarseness of voice will be measured using direct questions	Postoperative (one, 6 and 24 hours)
