Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Temperature of inspired gas at the Y piece will be measured.
Sterile water will be used for HH \& Mist nebuliser.
The suctioning of endotracheal tube (ETT) will be done once every 2 hourly by nurse/ doctor/trained personnel and additional suctioning if required.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Temperature of inspired gas at the Y piece will be measured as surrogate marker for quality of humidification. Continuous monitoring of temperature will be done using standard monitor.
The reusable HH will be subjected to disinfection between patients. Sterile water will be used for HH \& Mist nebuliser.
The suctioning of endotracheal tube (ETT) will be done once every 2 hourly by nurse/ doctor/trained personnel.
Based on patient's clinical condition , additional suctioning will be done. Frequency of additional suctioning , reason for suctioning will be noted.
Information regarding the age, sex, type of surgery of the patient, co-morbidity if any size of ETT, the time of commencement of humidification , duration of use of humidifier, time of extubation, any complication leading to discontinuation of humidifier, frequency of refilling of nebulizer chamber, volume of ETT before intubation etc. will be noted.
The amount of Endotracheal tube blockade caused by secretion will be measured immediately following extubation.
The volume of Endotracheal tube secretion / amount of blockade will be assessed by the following process-
* The bevel end \& Murphy's eye of the Endotracheal tube will be sealed using sterile insulating tape so that it become water tight. The tube will be gradually filled with measured amount of sterile fluid using small volume syringe to increase the accuracy of measurement. The amount of fluid it can hold will be measured \& noted.
* The volume of extubated tube will be measured in the similar way.
* The measured volume of the Extubated Endotracheal tube will be subtracted from the actual volume of the particular Sized ETT ( measured before intubation).
* The result obtained after this subtraction will be the volume of secretion or the volume of ETT that has been blocked.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Heated humidifier group
30 postoperative patients with overnight endotracheal intubation will be supplied humidified oxygen using Heated Humidifier (HH). Temperature of inspired gas at the Y piece will be measured as surrogate marker for quality of humidification. The suctioning of ETT will be done once every 2 hourly by nurse/ doctor/trained personnel.

30 patients requiring overnight intubation but breathing spontaneously without ventilatory support will be supplied humidified oxygen using Heated Humidifier(HH)
Mist humidifier group
30 postoperative patients with overnight endotracheal intubation will be supplied humidified oxygen using mist nebuliser. Temperature of inspired gas at the Y piece will be measured as surrogate marker for quality of humidification. The suctioning of ETT will be done once every 2 hourly by nurse/ doctor/trained personnel.
