title: [Postoperative changes of maximum inspiratory and expiratory pressures in 3 pneumonia cases occurring after surgery for empyema].
abstract: We examined preoperative and postoperative maximum inspiratory (MIP) and expiratory (MEP) pressures in 3 cases who died of postoperative pneumonia occurring more than one month after open drainage thoracotomy for empyema. All cases showed reduction of MIP and MEP to less than 20 cmH2O one month after surgery, then suffered of pneumonia. On the other hand, the other 3 cases with empyema who underwent open drainage thoracotomy and recovered without complication showed recovery of MIP and MEP one month after surgery. In conclusion, for the cases that underwent thoracic surgery, postoperative MIP and MEP are the index of respiratory condition such as deep diaphragmatic breathing and ability of efficient coughing, and can be an early prediction of late onset pneumonia after thoracic surgery.
