the cytology study is effective and reliable technique in intraoperative consultation. this study was performed to evaluate the accuracy of the cytology study in intraoperative consultation of the breast lesions. 125 specimens of the breast lesions were examined and studied in imam khomeini hospital during the years 1998-99. the sensitivity, specificity and accuracy for cytological method were ...

results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...

OBJECTIVES To investigate the risk factors and incidence of perioperative adverse effects from unsupplemented spinal anesthesia in preterm infants. Times to resumption of oral feeding and to home discharge were also evaluated. METHODS Perioperative data were collected prospectively for all preterm and former preterm infants who underwent inguinal hernia repair with spinal anesthesia at a tert...

A 30-year-old female at 24 weeks gestation presented with headache, hypertension and blurry vision. She was diagnosed with pre-eclampsia on chronic hypertension. An obstetrical emergency was called due to fetal heart rate decreasing to a nadir of 40bpm and the patient was taken for an emergent cesarean delivery. Prior to induction of anesthesia, the SpO2 was 92%. A rapid sequence induction was ...

General anesthesia is known to cause pulmonary atelectasis; in turn, atelectasis increases shunt, decreases compliance, and may lead to perioperative hypoxemia. One mechanism for the formation of atelectasis intraoperatively is ventilation with 100% oxygen. The goal of this review is to determine if research suggests that intraoperative ventilation with 100% oxygen leads to clinically significa...

background and objective: the main causes of nocturnal hypoxemia are pulmonary diseases or sleep related breathing disorders. in overlap syndrome, the co-existence of chronic obstructive pulmonary disease (copd) and ob-structive sleep apnea (osa), blood oxygen alteration, and hypercapnia may be more severe. we aimed to study hypox-emia markers in osa patients with or without copd. materials and...

We present a rare case of successful anesthetic management for a patient who had refractory hypoxia during liver transplantation (LT) with intraoperative veno-venous (VV) extracorporeal membrane oxygenation (ECMO) support. A 49 year-old female patient underwent living donor LT. After reperfusion of the grafted liver, graft congestion and massive oozing developed. Thus it was decided to reoperat...

Oxygen therapy, a lifeline for many critically ill patients, can be delivered in nonintubated patients via several devices. unlike patients with chronic hypoxemia, the long-term comfort and cosmetics of the patient are not a concern of intensivists; instead, the goal is to ensure adequate oxygen delivery to prevent hypoxemia. although hypoxemia is often corrected with oxygen therapy, care shoul...
