OBJECTIVE General anesthesia causes reduction of functional residual capacity. And this decrease can lead to atelectasis and intrapulmonary shunting in the lung. In this study we want to evaluate the effects of 5 and 10cmH2O PEEP levels on gas exchange, hemodynamic, respiratory mechanics and systemic stress response in laparoscopic cholecystectomy. METHODS American Society of Anesthesiologist...

BACKGROUND We studied which factor could predict aseptic loosening in ABG I hip prosthesis with hydroxyapatite coating. Aseptic loosening and periprosthetic osteolysis are believed to be caused, at least in part, by increased polyethylene (PE) wear rate via particle disease. Based on it, increased PE wear rate should be associated with aseptic loosening regardless of the type of implant. METH...

INTRODUCTION Prevention of pulmonary complications after coronary artery bypass graft is attended as a very important issue. The aim of this study was to evaluate the role of pulmonary rehabilitation before surgery for reducing the risk of pulmonary complications after surgery. METHODS In a randomized clinical trial, 60 patients undergoing heart surgery were randomly divided into two groups A...

BACKGROUND Hypoxemia is common during one-lung ventilation(OLV), predominantly due to transpulmonary shunt. None of the strategies tried showed consistent results. We evaluated the effectiveness of ventilating the operated, non-dependent lung (NDL) with small tidal volumes in improving the oxygenation during OLV. METHODS 30 ASA 1 and 2 patients undergoing elective, open thoracotomy were studi...

BACKGROUND Although Chiari-like malformation (CM) and syringomyelia (SM) have been described in many small breed dogs, the prevalence and clinical manifestations of this complex have not been documented in a large cohort of American Brussels Griffon (ABG) dogs. OBJECTIVES To characterize the clinical and magnetic resonance imaging (MRI) features of CM and SM in the ABG breed. ANIMALS Eighty...

OBJECTIVE To discuss the effect of edaravone on serum pulmonary surfactant protein A (SP-A) and arterial blood gas (ABG) in patients with thoracoscopic lobectomy. METHODS 40 lung cancer patients with right side of lobectomy were randomly divided into control group (group C, 20 cases) and edaravone group (group E, 20 cases). Group E was treated edaravone (1 mg/kg) between induction and skin in...

BACKGROUND Preoperative hypercapnia and hypoxemia are reportedly risk factors for postoperative complications. This study aimed to establish the long-term survival risk associated with abnormal preoperative arterial blood gases (ABGs) in patients with non-small cell lung cancer (NSCLC). METHODS This study involved 414 patients with stage I NSCLC who underwent lobectomy/bilobectomy with medias...

Objective
 The false sensorineural loss caused by otosclerosis
 due to stapes fixation is known as the Carhart notch.
 To examine changes in air-bone gap (ABG)
 and bone-conduction (BC) hearing thresholds by
 comparing preoperative postoperative
 audiometry results patients with chronic otitis media
 (COM), investigate effects of air conduction
 (AC) on B...

The ABG I cementless hip prosthesis has demonstrated unacceptably high rates of wear and osteolysis in our patients. We performed a retrospective study of 97 hips implanted between 1992 and 1998. Radiographic analysis revealed high rates of wear of the polyethylene liner with marked peri-acetabular osteolysis. Clinical examination indicated that many of these patients were initially asymptomati...

Neonates with respiratory distress syndrome (RDS), who are treated according to INSURE protocol; require arterial blood gas (ABG) analysis to decide on appropriate management. We conducted this study to investigate the validity of pulse oximetry instead of frequent ABG analysis in the evaluation of these patients. From a total of 193 blood samples obtained from 30 neonates <1500 grams with RDS,...
