Objective To evaluate the effects of penehyclidine hydroehloride as an atropine alternative on angioearpy and glandular secretions when premedieated in ketamine complex total intravenous anesthesia(TIVA)in children.Methods Forty patients aged 3-10 years undergoing ketamine and propofol complex TIVA were randomly divided into two groups.Penehyclidine hydrochloride(group P,n=20)or atropine(group A,n=20)was premedicated intramuscularly 30 min before anesthesia.Heart rate(HR),mean arterial pressure(MAP),breath rate(R)and the amount of saliva secretion(SS)were recorded before premedication(0 min),10 min,20 min,30 min,60 min and 150 min after.Results (1)SS reduced significantly 20 min,30 min and 60 min after premedication in both groups(P＜0.01),and in 150 min,it was still in a significantly reduced level in group P(P＜0.01),which was significantly lower than that in group A(P＜0.01).(2)MAP,HR and R in group P showed no significant differences before and after premedication(P＞0.05).But in group A,HR increased significantly at 20 min,30 min and 60 min after premedication(P＜0.05 or＜0.01),MAP increased significantly at 30 min and 60 min after premedication(P＜0.01),and meanwhile of them were also significantly higher than those in group P(P＜0.05 or＜0.01).Conclusions Penehychdine hydrochloride can effectively reduce respiratory glandular secretion with longer persistence,and nearly has no influence on HR and blood pressure,which suggests it could be a superior to atropine alternative as an anesthesia premedication in children.

Major obstetric hemorrhage (MOH) may endanger the life of maternal during the perioperative period. Its highly efficient management involves multidisciplinary co-operation and is a complex clinical emergency situation which needs teamwork to complete. Anesthesiologist, as the key member of the obstetric MOH management team, should actively cooperate with the obstetricians once they decide to perform an emergency procedure for the parturient. They should possess perfect skill in resuscitation and rich experiences for assessment of MOH. They also should be professional in monitoring and caring for the critically ill patient. Constantly simulation training also should be actively carried out for MOH. In this review, the definition and etiology of MOH, drug and surgical treatment, anesthesia management (including preparation before anesthesia, hemorrhagic shock assessment, choice of anesthesia methods, blood transfusion, blood cell salvage, coagulation function and hemodynamic monitoring) were reviewed, and the conclusions were just for references.

Cardiac arrest in pregnancy is the emergency sereve case in clinic,which can threaten life and health of the fetus and pregnant women.Pregnancy cardiac arrest once happened,providing health care providers should start high quality chest compressions immediately,open the airway and commence ventilation,activate an emergency call system in which all providers in the maternal/neonatal resuscitation teams.We read from several aspects of 2014 the United States society for Obstetric Anesthesia and Perinatology consensus statement on the management of cardiac arrest in pregnancy in order to improve the cardiopulmonary resuscitation quality of pregnant women after cardiac arrest and optimize maternal and neonatal outcomes.
