Objective To investigate the safety and efficiency of using Succinylcholine as premedication for non-urgency intubation in prematurity.Methods During Jan.to Jul.2007,in Ottawa General Hospital and Children's Hospital of Eastern Ontario NICU,the prematurity who were received non-urgency intubation were divided into 2 groups as premedication group(group A)and non-premedication group(group B).Premedications in group A were applied Atropine,Fentanyl and Succinylcholine;premedications in group B were applied Atropine and Fentanyl.The same procedures were done according to the protocol in 2 groups.The basical information,one attempt successful intubation,total attempts,Goldberg scores and side effects were compared between both groups.Results Forty-four cases were involved in the study,25 cases in group A,19 cases in group B,there was no significant difference in patients' basical information between both groups.One attempt successful intubation was 56.0%(14 cases)in group A,higher than that in group B [21.1%(4 cases)],which had significant diffe-rence between 2 groups(P0.05).Conclusions Atropine,Fentanyl and Succinylcholine are safe as the premedication used in prematurity,which can improve one attempt successful intubation avoiding glottal injury of repeating attempts.It also can helps young physician to be familiar with the intubation techniques,premedication is recommended to teaching hospital.

OBJECTIVETo investigate the effect of intra-operative intravenous fluids on post-operative hemodynamic stability.

METHODSWe performed a retrospective cohort study of 98 preterm infants who underwent a patent ductus arteriosus (PDA) ligation in one NICU between 2001 and 2007. The primary outcome was the need for cardiotropic support within 24 hrs of ligation.

RESULTSTwenty-seven infants (28%) required post-operative cardiotropic support. The amount of intra-operative fluids varied between 0 and 50.4 mL/kg (median: 10.2 mL/kg). No intra-operative fluid was recorded in 26 patients. Fluids were not associated with the need for post-operative cardiotropic support (P=0.10). Using a multivariate logistic regression model, age at ligation, weight at ligation and pre-operative FiO2 were significant predictors of post-operative cardiotropic support.

CONCLUSIONSIntra-operative fluids do not appear to be associated with the need for post-operative cardiotropic support. A prospective cohort study may help identify modifiable risk factors and improve outcomes in this population.
