How do anaesthesiologists treat malignant hyperthermia in a full-scale anaesthesia simulator?

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 8 2001
T. i Gardi
Background: Clinical malignant hyperthermia (MH) is rare and usually occurs unexpectedly. Prompt diagnosis and correct treatment is crucial for survival of the patient developing fulminant MH. The aims of the present study were to investigate whether anaesthesiologists could make a correct diagnosis of MH and to evaluate their treatment of fulminant MH in a simulator. Methods: Thirty-two teams (one anaesthesiologist/one nurse anaesthetist) were exposed to an event of clinical MH in a full-scale simulator. Their performance was videotaped for retrospective analysis of the treatment on the basis of the recommendations of the Danish Malignant Hyperthermia Register. Results: All 32 teams asked the surgeon to terminate the surgery as fast as possible, switched off the vaporiser and administered 100% oxygen. Although all intended to hyperventilate the patient, only 14 teams actually managed to perform the hyperventilation. Most problems were found in teams that switched to manual ventilation. All teams treated the patient with dantrolene, and symptomatic treatment was initiated by all even though some elements of the full treatment were lacking, possibly due to the limited time available. Conclusion: All teams diagnosed MH in the simulator satisfactorily. The surprising negative finding was that more than half of the participants failed to hyperventilate the "patient" although they intended to do so. This investigation shows that the problem in these teams' treatment of MH was more a question of practical management of the resources than lack of theoretical knowledge. [source]

Incidence of postoperative nausea and vomitingin paediatric ambulatory surgery

PEDIATRIC ANESTHESIA, Issue 8 2002
I. Villeret
SummaryBackground: We performed a prospective descriptive study over a 5-month period to determine the incidence of postoperative nausea and vomiting (PONV) during the first 24 h following elective ambulatory paediatric surgery, excluding head and neck procedures. Methods: Four hundred and seven patients, aged 15 days to 16 years, were analysed prospectively. Results: The incidence of PONV was 9.4%, occurring most frequently during the first 3 h after anaesthesia and in hospital but rarely during the journey home. It was associated with age, previous history of PONV, tracheal intubation or use of the laryngeal mask airway (LMAÔ), controlled or manual ventilation, opioids and absence of oral intake of liquids or solids. Conversely, type of surgery, premedication, induction mode, association of regional anaesthesia, inhaled nitrous oxide, duration of anaesthesia, stay in the postanaesthesia care unit and duration of journey after discharge were not significantly associated with PONV. Conclusions: PONV never induced complications or delayed patient discharge and curative treatment was rapidly effective. [source]


A comparison of the laryngeal mask airway with the facemask and oropharyngeal airway for manual ventilation by first responders in children

ANAESTHESIA, Issue 12 2009
A. E. Blevin
Summary In adults, first responders to a cardiopulmonary arrest provide better ventilation using a laryngeal mask airway than a facemask. It is unclear if the same is true in children. We investigated this by comparing the ability of 36 paediatric ward nurses to ventilate the lungs of 99 anaesthetised children (a model for cardiopulmonary arrest) using a laryngeal mask airway and using a facemask with an oropharyngeal airway. Anteroposterior chest wall displacement was measured using an ultrasonic detector. Nurses achieved successful ventilation in 74 (75%) of cases with the laryngeal mask airway and 76 (77%) with facemask and oropharyngeal airway (p = 0.89). Median (IQR [range]) time to first breath was longer for the laryngeal mask airway (48 (39,65 [8,149])) s than the facemask/airway (35 (25,53 [14,120]) s; p < 0.0001). In 10 cases (10%) the lungs were ventilated using the laryngeal mask airway but not using the facemask/oropharyngeal airway. We conclude that ventilation is achieved rapidly using a facemask and oropharyngeal airway, and that the laryngeal mask airway may represent a useful second line option for first responders.

Supplementary oxygen and risk of childhood lymphatic leukaemia

ACTA PAEDIATRICA, Issue 12 2002

Aim: Childhood leukaemia has been linked to several factors, such as asphyxia and birthweight, which in turn are related to newborn resuscitation. Based on the findings from a previous study a population-based case-control study was performed to investigate the association between childhood leukaemia and exposure to supplementary oxygen and other birth-related factors. Methods: Children born in Sweden and diagnosed with lymphatic leukaemia between 1973 and 1989 (578 cases) were individually matched by gender and date of birth to a randomly selected control. Children with Down's syndrome were excluded. Exposure data were blindly gathered from antenatal, obstetric and other standardized medical records. Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated by conditional logistic regression. Results: Resuscitation with 100% oxygen with a facemask and bag immediately postpartum was significantly associated with an increased risk of childhood lymphatic leukaemia (OR = 2.57, 95% CI 1.21,6.82). The oxygen-related risk further increased if the manual ventilation lasted for 3 min or more (OR = 3.54, 95% CI 1.16,10.80). Low Apgar scores at 1 and 5 min were associated with a non-significantly increased risk of lymphatic leukaemia. There were no associations between lymphatic leukaemia and supplementary oxygen later in the neonatal period or other birth-related factors. Conclusion: Resuscitation with 100% oxygen immediately postpartum is associated with childhood lymphatic leukaemia, but further studies are warranted to confirm the findings. [source]
