ABSTRACT

BACKGROUND: We evaluated the use of dexmedetomidine to facilitate the weaning of delirious postoperative patients from mechanical ventilation. METHODS: We included 72 consecutive patients who underwent elective cardiac surgery in this prospective observational study. Each patient had failed at least 1 trial of continuous positive airway pressure (CPAP) and had agitation. Patients were assessed with the Richmond Agitation-Sedation Scale (RASS) and the Confusion Assessment Method for the Intensive Care Unit (CAMICU) 12 to 18 hours after their admission to the ICU. Midazolam and fentanyl were then given to all patients according to the sedation protocol. At 36 hours in the ICU, patients who had agitation and an inability to wean were randomly divided into 2 groups: group M, 34 patients who continued to follow the routine sedative protocol; and group D, 38 patients who were given dexmedetomidine. Arterial blood gas measurements, hemodynamic parameters, and time to extubation were recorded. Statistical analysis was performed with GraphPad InStat (version 2.02 for DOS). RESULTS: All patients tested positive in the CAM-ICU assessment, and all had a delirium diagnosis. The 38 patients in group D tolerated a spontaneous breathing trial with CPAP and were extubated after a mean (±SD) of 49.619 ± 6.96 hours. The 2 groups had significantly different extubation times (58.389 ± 3.958 hours versus 49.619 ± 6.96 hours). The 2 groups had significantly different RASS scores at 48 and 60 hours and significantly different heart rates and PO2 values at 12 and 24 hours. The 2 groups showed no significant differences with regard to hemodynamic parameters. CONCLUSIONS: Dexmedetomidine may help to eliminate the emergence of agitation and can be a good treatment choice for the delirium state after cardiac surgery.

ABSTRACT

BACKGROUND AND AIM: Patients undergoing surgical procedures through median sternotomy have reduced pulmonary function in the postoperative period. Our study was designed to evaluate the effect of pleural integrity in terms of respiratory functions and pain score after coronary bypass procedures. METHODS: In a randomized, prospective study we evaluated 320 patients in two groups. Group I (n = 160) patients were the patients whose pleural cavity was intact while internal mammary artery (IMA) harvesting, and in group II (n = 160) the pleural cavity of the patients was opened. They matched in terms of postoperative respiratory functions and pain score. RESULTS: FEV1 (%) and FEV1/FVC levels at the postoperative fifth day were significantly lower in group II (I = 71.5 +/- 4.9 vs. II = 63.5 +/- 8.3 and I = 24.1 vs. II = 22.1), respectively (p < 0.05). The rate of postoperative pleural effusions and atelectasis at the postoperative fifth day were significantly higher in group II (I = 35%, 15% vs. II = 48%, 35%), respectively (p < 0.05). The pain score was higher in group II at postoperative fifth day. CONCLUSIONS: All patients undergoing cardiac surgery suffer deterioration in pulmonary functions. Pleurotomy seems to compound this with increased rates of atelectasis and pleural effusions. Moreover, preserving pleural integrity provides beneficial effects on pain score after coronary operations especially in the early postoperative period.

ABSTRACT

PURPOSE: Pectus deformities and cardiac problems sometimes require simultaneous surgery. We report our experience of performing this surgery and review the relevant literature. METHODS: We performed simultaneous pectus deformity correction and open-heart surgery in six patients between 1999 and 2006. The pectus deformities were pectus carinatum in one patient and pectus excavatum in five patients. The cardiac problems were coronary artery disease in one patient, an atrioseptal defect (ASD) with a ventricular septal defect (VSD) in one, a VSD in one, mitral valve insufficiency with left atrial dilatation in one, and an ascending aortic aneurysm with aortic valve insufficiency caused by Marfan's syndrome in two. We corrected the pectus deformities using the modified Ravitch's sternoplasty in all patients. First, while the patient was supine, we resected the costal cartilage; then, after completing the cardiac surgery, the sternum was closed and the additional time required for the pectus operation was calculated for each patient. Patients were examined 1, 4, and 6 months postoperatively. RESULTS: The average operation time was 102 min, and there were no major complications. The pectus bars were removed 4-6 months postoperatively. Good cardiac and cosmetic results were achieved in all patients, who were followed up for 5 years. CONCLUSIONS: Concomitant pectus deformity correction and open-heart surgery can be performed safely, eliminating the risks of a second operation in a staged procedure.

ABSTRACT

Hydatid disease rarely involves the aortic wall. We report a case of hydatidosis involving the ascending aorta and the left atrium. The patient underwent replacement of the ascending aorta with a prosthetic Dacron graft and left atrial cystectomy. At the 6-month follow-up, she was leading a normal life.
