Effectiveness of Open Suction Vs Closed Suction Method on cardio respiratory parameters among patients with mechanical ventilators, in selected hospital, Chennai

Tracheal suctioning is an essential component of airway management for patients requiring mechanical ventilation and it is one of the most common invasive procedures performed in any critical care unit today. The primary goals of the suctioning procedure are secretion removal in order to maintain airway patency, decrease airway resistance, achieve optimal oxygenation. Complications of tracheal suctioning include respiratory and cardiac arrest, hemodynamic instability, hypoxia, increased intracranial pressure, bronchospasm, hemorrhage, and tracheal damage. Tracheal secretions in mechanically ventilated patients are removed using a catheter via the endotracheal tube. The suction catheter can be introduced by disconnecting the patient from the ventilator (open suction system) or by introducing the catheter into the ventilatory circuit (closed suction system). The research approach used in this study was quantitative approach. The research design is non randomized clinical trial, time series study. The study was conducted in Malar Hospital, Chennai. Objective of the study was to assess the effectiveness of open suction Vs closed on cardio respiratory parameters among patients with mechanical ventilators. A total of 40 patients with mechanical ventilator who full fill the inclusive criteria were selected using purposive sampling technique, cardiac monitor was used to assess the cardio respiratory parameters, suctioning procedure done daily. The data analysis was done by using descriptive and inferential statistics. The study finding revealed that in cardiac parameter under open there is significant changes in open suction method in heart rate, MAP and respiration, SPO2 and ‘t’ value is 10.32 and P = 0.001 null hypothesis was rejected. In closed suction there is no significant changes in heart rate, MAP, oxygen saturation and respiration rate and ‘t’ value is 4.67 and P = 1.0. Null hypothesis was accepted. The nurse play a vital role in assessing the cardiac monitor while doing suctioning to prevent cardio respiratory complications
