The purpose of this study was to find out the impact of acute respiratory acidosis on serum potassium level during laparoscopy. The study was performed on ninety patients who underwent laparoscopic surgery. Ventilation parameters were kept constant throughout the study. Samples for assessment of blood gases were collected in the following sequence: before pneumoperitoneum, a the 20th minute of pneumoperitoneum, at the 60th minute of pneumoperitoneum, and after extubation. The systolic, diastolic pressures and heart rate were recorded simultaneously. Before pneumoperitoneum, heart rate, systolic and diastolic pressures were reduced according to baseline values. With the induction of pneumoperitoneum, both systolic and diastolic pressures returned to the baseline levels except the heart rate. There was a statistically significant increase in potassium level (Control: 3.49 mEq.L(-1), determined high level: 3.75 mEq.L(-1)). Electrolytes, especially potassium, should be monitored during laparoscopy utilizing CO2 pneumoperitoneum and when necessary, ventilatory parameters should be adjusted. 相似文献

Testicular torsion is an important clinical urgency. Similar mechanisms occurred after detorsion of the affected testis as
in the ischemia reperfusion (I/R) damage. This study was designed to investigate the effects of erythropoietin (EPO) treatment
after unilateral testicular torsion. Fifty male Sprague-Dawley rats were divided into five groups. Group 1 underwent a sham
operation of the right testis under general anesthesia. Group 2 was same as sham, and EPO (3,000 IU/kg) infused i.p., group
3 underwent a similar operation but the right testis was rotated 720° clockwise for 1 h, maintained by fixing the testis to
the scrotum, and saline infused during the procedure. Group 4 underwent similar torsion but EPO was infused half an hour before
the detorsion procedure, and in group 5, EPO was infused after detorsion procedure. Four hours after detorsion, ipsilateral
and contralateral testes were taken out for evaluation. Treatment with EPO improved testicular structures in the ipsilateral
testis but improvement was less in the contralateral testis histologically, but EPO treatment decreased germ cell apoptosis
in both testes following testicular IR. TNF-α, IL-1β, IL-6 and nitrite levels decreased after EPO treatment especially in
the ipsilateral testis. We conclude that testicular I/R causes an increase in germ cell apoptosis both in the ipsilateral
and contralateral testes. Eryhropoietin has antiapoptotic and anti-inflammatory effects following testicular torsion. 相似文献

Variant angina is generally a benign disease with self limiting symptoms. But in some cases serious ventricular arrhythmias which can lead to death can be seen. In this paper we present a case of variant angina who subsequently developed polymorphic ventricular tachycardia and was treated successfully with long acting nitrate and calcium channel blockade therapy. 相似文献
