Comparıng early and late extubatıon effects after thoracotomy on fev1, fvc parameters and paın

Thoracotomy, a technique that the thorax is opened with surgical intervention,often used in Thoracic Surgery for pulmonary resection operation and rarely used inCardiovascular Surgery for Cardiopulmonary Bypass. Damage of the soft tissues,muscles, ribs and peripheral nerves with thoracotomy incision causespostthoracotomy pain known as the most severe postoperative pain. In postoperativeperiod due to pain, reduction occurs in FEV1 and FVC parameters which areindicators of lung function. Decreasing lung capacity and volumes, inadequate coughand refuse to respiratory therapy due to pain as a result of increased risk ofpostoperative pulmonary complication.In our study, after thoracotomy early vs late extubation effects on perception ofpain severity and lung function were investigated in two groups. Early extubationgroup consists of 30 patients also late extubation group consists of 30 patients.Unlike the early extubation group of late extubation group by applying postoperativesedation was extubated two hours later. FEV1, FVC and FEV1/FVC values inpreoperative and postoperative period were analyzed. Severity of pain wasquestioned with Visual Analog Scale (VAS).Each of two groups have recorded a serious reduction in FEV1 and FVCparameters in postoperative period. Although there were lower VAS score in lateextubation group, we have founded no significant difference between two groups interms of severity of pain effects on the lung function.Key words: Thoracotomy, Early Extubation, Late Extubation, PostoperativePain, Postoperative VAS, Postoperative PFT.
