The Effect of iv. Lidocaine On Postoperative Respiratory Comlications of Isoflurane Anaesthesia In Paediatrics

Background: Inhalation anesthesia using Isoflurane in pediatrics is related to airway irritability, coughing, breath holding, and laryngeal spasm. This study aims to determine the effect of i.v. Lidocaine 5 minutes before emergence on the incidence and severity of postoperative respiratory complications of Isoflurane in a pediatric population. Method: A randomized clinical trial study conducted in Children Welfare Hospital included 118 unpremeditated children, aged 6 months to 10 years who were enrolled in the study and randomized to receive iv. Lidocaine (n=54, Group A) and Not receiving Lidocaine (n=64, Group B). Were all induced with Propofol and maintained with Isoflurane. The occurrence of coughing, breath-holding, laryngospasm, bronchospasm, and secretion was recorded. The severity of each complication was graded on a scale of 0-3. Results: The incidence of coughing (31% vs 56%) and laryngospasm (22% vs 59%), coughing severity score (26 vs 72), breath-holding severity score (16 vs 38), and the need to change to a higher FiO2 (4% vs 11%) were more frequent in Group A than in Group B (p<0.05). There was no difference regarding the incidence of breath-holding (26% vs 31%) and secretion (30% vs 31%). Conclusions: i.v. Lidocaine 5 minutes before emergence from anesthesia reduces the frequency and severity of coughing, the frequency of laryngospasm, the severity of breath-holding, and the need to change to higher FiO2 in pediatrics.

Anesthesia in a child operated for cleft lip associated with Patau's syndrome / Anestesia em criança operada para lábio leporino associado à síndrome de Patau

Abstract Patients with Patau's syndrome (Trisomy 13) have multiple craniofacial, cardiac, neurological and renal anomalies with very less life expectancy. Among craniofacial anomalies cleft lip and palate are common. These craniofacial and cardiac anomalies present difficulties with anesthesia. We therefore describe the anesthetic management in the case of a Trisomy 13 child for operated for cleft lip at 10 months of age.

Resumo Os pacientes com síndrome de Patau (trissomia 13) apresentam várias anomalias craniofaciais, cardíacas, neurológicas e renais, com expectativa de vida bem menor. Entre as anomalias craniofaciais, o lábio leporino e a fenda palatina são comuns. Essas anomalias craniofaciais e cardíacas apresentam dificuldades na anestesia. Portanto, descrevemos o manejo anestésico em uma criança de 10 meses com trissomia 13 submetida à cirurgia de lábio leporino.

Effect of nitrous oxide on cuff pressure of ProSeal laryngeal mask airway during pediatric anesthesia / 上海第二医科大学学报

Objective To evaluate the effect of nitrous oxide(N2O) on the cuff pressure of ProSeal laryngeal mask airway(PLMA) in pediatric anesthesia. Methods Thirty-two pediatic patients were enrolled and divided into two groups randomly.PLMA cuffs were inflated with air(Group A) or 50% N2O/oxyen(Group N) to 20 mmHg as initial pressure.The intracuff pressure was monitored during anesthesia with 50% N2O in oxygen. Results Intracuff pressure increased to(40.6?9.3) mmHg in Group A and slightly decreased in Group N.Deflation volume in Group A was much more than that in Group N[(4.4?2.3) mL vs(2.6?1.0) mL,P
