研究概览
简要总结
60 post operative patients who are kept intubated overnight & are spontaneously breathing will be either supplied humidified oxygen Heated Humidifier(HH) or conventional mist nebulizer.
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.
详细描述
60 post operative patients who are kept intubated overnight & are spontaneously breathing will be selected in Tata Memorial Hospital (TMH), Mumbai. 30 patients will be supplied through humidified oxygen using FISHER & PAYKEL MR 370 Heated Humidifier(HH) & 30 patients through conventional mist nebulizer.
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.

研究组 & 干预措施
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.
干预措施: heated humidifier (Device)
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.
干预措施: mist humidifier (Device)
结局指标
主要结局
Extent of Blockade of Endotracheal Tube Assessed by Change in the Endotracheal Tube Volume
时间窗: At baseline just before intubation and 24 hours from time of ICU admission
The bevel end \& Murphy's eye of the Endotracheal tube was sealed using sterile insulating tape so that it becomes water tight. The tube was 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 was measured \& noted
Assess the Increase in Nurses Work Load
时间窗: At baseline just before intubation and 24 hours from time of ICU admission
Investigators will assess nursing workload by frequency of filling of humidifier chamber.
