Objectives: Determine incidence of complications such as difficult or failed intubation, hypoxemia, hypotension, and bradycardia in children undergoing rapid sequence intubation (RSI) in a pediatric anesthesia department in a tertiary care children’s hospital. Aim: To establish a benchmark to be used by other institutions and nonanesthesiologists performing RSI in children. Background: RSI is being increasingly performed in the nonoperating room setting by nonanesthesiologists. No published studies exist to establish a benchmark of intubation success or failure and complications in this patient population. Methods/Materials: Retrospective cohort analysis of children aged 3–12 undergoing RSI from 2001 to 2006. Results: One thousand seventy children underwent RSI from 2001 to 2006. Twenty (1.9%) developed moderate hypoxemia (SpO2 80–89%), 18 (1.7%) demonstrated severe hypoxemia (SpO2 < 80%), 5 (0.5%) developed bradycardia (heart rate <60), and 8 (0.8%) developed hypotension (systolic blood pressure <70 mmHg). One patient had emesis of gastric contents but no evidence of pulmonary aspiration or hypoxemia. Eighteen (1.7%) children were noted to be difficult to intubate and required more than one intubation attempt. All were eventually intubated without significant complications. Patients between 10 and 19 kg had a higher incidence of severe hypoxemia when compared with older children (P < 0.001). There was no association between choice of muscle relaxant and any complication. Conclusions: In our cohort of 1070 children who underwent RSI, difficult intubation was encountered in 1.7% and transient oxyhemoglobin desaturation occurred in 3.6%. Severe hypoxemia was more likely in children <20 kg. There were no children who could not be intubated, and there were no long‐term or permanent complications. 相似文献

Pulmonary aspiration of gastric content is a significant cause of anaesthesia-related morbidity and mortality. High-quality prospective randomised evidence to support prevention strategies, such as rapid sequence intubation, is difficult to generate due to well-described practical, ethical and methodological barriers. We aimed to generate an understanding of worldwide practice through surveying clinically practicing anaesthetists and airway experts. Our survey was designed to assess the influence of: departmental standards; patient factors; socio-economic factors; training; and supervision. We surveyed 10,003 anaesthetists who responded to an invitation to participate on LinkedIn. We then surveyed 16 international airway experts on the same content. When asked about a hypothetical patient with intestinal obstruction, respondents expressed preferences for [OR (95%CI)]: the head-up or -down position 4.26 (3.98–4.55), p < 0.001; nasogastric tube insertion 29.5 (26.9–32.3), p < 0.001; and the use of cricoid force 2.80 (2.62–3.00), p < 0.001, as compared with a hypothetical patient without intestinal obstruction also requiring rapid sequence intubation. Respondents from lower income countries were more likely to prefer [OR (95%CI]: the supine position 2.33 (2.00–2.63), p < 0.001; nasogastric tube insertion 1.29 (1.09–1.51), p = 0.002; and cricoid force application 2.54 (2.09–3.09), p < 0.001 as compared with respondents from higher income countries for a hypothetical patient with intestinal obstruction. This survey, which we believe is the largest of its kind, demonstrates that preferences for positioning, nasogastric tube use and cricoid force application during rapid sequence intubation vary substantially. Achieving agreed consensus may yield better training in the principles of rapid sequence intubation. 相似文献

Pre-oxygenation using high-flow nasal oxygen can decrease the risk of desaturation during rapid sequence induction in patients undergoing emergency surgery. Previous studies were single-centre and often in limited settings. This randomised, international, multicentre trial compared high-flow nasal oxygen with standard facemask pre-oxygenation for rapid sequence induction in emergency surgery at all hours of the day and night. A total of 350 adult patients from six centres in Sweden and one in Switzerland undergoing emergency surgery where rapid sequence induction was required were included and randomly allocated to pre-oxygenation with 100% oxygen using high-flow nasal oxygen or a standard tight-fitting facemask. The primary outcome was the number of patients developing oxygen saturations <93% from the start of pre-oxygenation until 1 min after tracheal intubation. Data from 349 of 350 patients who entered the study were analysed (174 in the high-flow nasal oxygen group and 175 in the facemask group). No difference was detected in the number of patients desaturating <93%, five (2.9%) vs. six (3.4%) patients in the high-flow nasal oxygen and facemask group, respectively (p = 0.77). The risk of desaturation was not increased during on-call hours. No difference was seen in end-tidal carbon dioxide levels in the first breath after tracheal intubation or in the number of patients with signs of regurgitation between groups. These results confirm that high-flow nasal oxygen maintains adequate oxygen levels during pre-oxygenation for rapid sequence induction. 相似文献

The effectiveness of labetalol (a combination nonselective beta and alpha-1-adrenergic receptor antagonist) in modifying hemodynamic responses associated with rapid sequence induction and tracheal intubation was evaluated. In a double-blind study, 24 ASA physical status I or II male patients scheduled for elective surgery were given either IV labetalol, 0.25 mg/kg (n = 8) or 0.75 mg/kg (n = 8), or a saline placebo (n = 8). Five minutes later, patients were given oxygen by mask and IV vecuronium, 0.01 mglkg. Ten minutes after giving labetalol or placebo, cricoid pressure was applied and anesthesia was induced with IV sodium thiopental (4 mg/kg) and succinylcholine (1.5 mg/kg) 1 minute prior to intubation. The mean duration of laryngoscopy was 17 ± 3 seconds. Prior to induction, the 0.25 mg/kg and 0.75 mg/kg) doses of labetalol significantly (p < 0.05) reduced mean arterial pressure by 4.4 ± 1.9 and by 8.6 ± 2.0 mmHg, respectively, but did not significantly alter heart rate or cardiac output. The 0.75 mg/kg) dose of labetalol also significantly (p < 0.05) decreased total peripheral resistance by 10.1 ± 3.0%. Within 30 seconds after intubation, patients in all three groups exhibited increases in heart rate, mean arterial pressure, total peripheral resistance, and rate pressure product and a decrease in stroke volume. However, patients in the 0.25 and 0.75 mg/kg) labetalol groups, compared to those in the placebo group, had significantly lower increases in peak heart rate (33 ± 2 and 27 ± 3 vs. 44 ± 7 beats/minute), peak mean arterial pressure (38 ± 6 and 38 ± 7 vs. 58 ± 7 mmHg), and peak rate pressure product (7,726 ± 260 and 7,215 ± 300 vs. 14,023 ± 250 units). The results show that these doses of labetalol significantly blunt, but do not completely block, autonomic responses to rapid sequence induction and intubation. 相似文献

BACKGROUND: The perceived safety of the use of succinylcholine is based on the fact that recovery from its effects will occur before oxygen desaturation occurs in case of failure to intubate or ventilate. The purpose of this study was to examine the incidence of oxygen desaturation after the use of succinylcholine prior to resumption of spontaneous ventilation following four different preoxygenation techniques. METHODS: Twenty-five patients each were randomly allocated to preoxygenation with 4 deep breaths of 100% oxygen or by breathing oxygen for 1, 3 or 5 min following which they received a rapid sequence induction of anaesthesia with fentanyl 1 microg kg(-1), a sleep dose of thiopentone and succinylcholine 1 mg kg(-1). Oxygen saturation was monitored continuously using a finger probe. Ventilation was not assisted unless the saturation decreased to 相似文献

BACKGROUND: The role of pre-hospital trauma care and the effect of pre-hospital rapid sequence intubation (RSI) on patient outcome are still not clear. This study evaluated the impact of pre-hospital trauma care by emergency physicians (EP) on mortality from severe traumatic brain injury (TBI) and a 180-day Glasgow Outcome Scale (GOS). METHODS: A 48-month parallel non-controlled cohort study compared a group of 64 patients with severe TBI [Glasgow Coma Scale (GCS) < 9; Injury Severity Score (ISS) > 15] who received pre-hospital advanced life support (ALS) with RSI and were transported to the hospital by EPs (EP group), with a group of 60 patients who did not receive pre-hospital ALS with RSI [emergency medical technicians (EMT) group]. RESULTS: There were no significant statistical differences between the groups in age (P= 0.79), mechanism of injury (P= 0.68), gender (P= 0.82), initial GCS (P= 0.63), initial SaO(2) in the field (P= 0.63), initial systolic blood pressure in the field (P= 0.47) and on-scene time (P= 0.41). In the EP group, there was significantly better first hour survival (97% vs. 79%, P= 0.02), first day survival (90% vs. 72%, P= 0.02), better functional outcome (GOS 4-5: 53% vs. 33%, P < 0.01; GOS 2-3: 8% vs. 20%, P < 0.01) and shortened hospitalization time in intensive care unit (ICU) (P= 0.03) and other departments (P= 0.04). In total hospital mortality, we detected no differences between both groups [EP group: 40% (95% CI: 34-45%) vs. EMT group 42% (95% CI: 36-47%, P= 0.76], except in a subgroup of patients with GCS 6-8 where there was significantly lower total hospital mortality in the EP group (24% vs. 78%, P < 0.01). CONCLUSION: After starting the trauma care system with emergency physicians in our region, there was a decrease in the number of deaths on hospital admission, a reduction in hospital mortality in the GCS group 6-8, a change in the temporal distribution of deaths, an improvement in functional neurological outcome and shortened hospitalization time. 相似文献

The haemodynamic response to endotracheal intubation and changes in the QT interval of ECG during anaesthetic induction were studied in 68 healthy children (5.5 years). The children were pretreated double-blindly with either alfentanil 10 micrograms/kg (A10), 25 micrograms/kg (A25), 50 micrograms/kg (A50) or saline (control) (17 children in each group) i.v. 1 min before thiopentone 5 mg/kg. The trachea was intubated after suxamethonium 1.5 mg/kg. Central nervous system excitation was seen in four of 17 and in one of 17 children after alfentanil 50 and 25 micrograms/kg, respectively. After intubation, heart rate increased significantly in the control group, remained at initial levels in the A10 and A25 groups and decreased in the A50 group. A pressor response to intubation was seen in the control and A10 groups. The QT interval was significantly prolonged after suxamethonium in the control and A10 groups, but remained at baseline levels in the A25 and A50 groups. Ventricular ectopic beats were only seen in 2/17 children in the control group. In conclusion, alfentanil 25 microgram/kg is ideal for preventing the haemodynamic response to endotracheal intubation and prolongation of the QT interval, a sign of sympathoadrenal activation, before induction of intravenous anaesthesia in children. 相似文献

Sevoflurane (12% and 8%) inhalational induction in children 总被引:3,自引:0,他引:3
Chawathe M Zatman T Hall JE Gildersleve C Jones RM Wilkes AR Aguilera IM Armstrong TS 《Paediatric anaesthesia》2005,15(6):470-475
BACKGROUND: Sevoflurane induction of anesthesia is frequently used in children. Rapidly performed inhalational induction may reduce excitation during early anesthesia. Increasing the total anesthetic MAC delivered to patients can be achieved by increasing volatile concentration or adding nitrous oxide. The latter reduces inspired oxygen concentration delivered, which may not be desirable. Even 8% sevoflurane induction is associated with excitation. A system capable of delivering 12% sevoflurane using two tandem vaporizers has been developed. METHODS: A randomized double blind study was undertaken to assess whether 12% sevoflurane offered any advantage over 8% in time and quality of induction. Sixty children aged 5-10 years were recruited and received either 12 or 8% sevoflurane. Time to loss of eyelash reflex, central pupils, incidence of adverse events, induction quality, systolic blood pressure and heart rate were recorded. RESULTS: Twelve percent sevoflurane reduced time to loss of eyelash reflex compared with 8% [mean (sd): 35 (12) and 46 (14) P<0.05], but the reduction was only 10% higher than the error in the measurement (assessment every 10 s). Twelve percent sevoflurane offered significantly better quality of induction (P<0.05). There was no difference in cardiovascular stability between groups, although heart rate rose significantly in both groups. Maintaining sevoflurane at 12% for 4 min caused significant amounts of apnea (69% with 12% and 38% with 8%, P<0.05). CONCLUSION: Twelve percent sevoflurane offers a smoother anesthesia induction than 8% in children of this age with no additional consequences for the cardiovascular system. 相似文献

Comparison of rocuronium and suxamethonium for rapid tracheal intubation in children 总被引:5,自引:0,他引:5
BACKGROUND: The purpose of our study was to determine whether a smaller dose of rocuronium than previously reported could provide similar intubating conditions to suxamethonium during rapid-sequence induction of anaesthesia in children. METHODS: One hundred and twenty ASA I, unpremedicated children, aged 1-10 years, who were undergoing elective surgery, were randomized into three groups to receive rocuronium 0.6 mg.kg-1, rocuronium 0.9 mg.kg-1 or suxamethonium 1.5 mg.kg-1. The study was double-blinded, anaesthesia and timing of injection was standardized to alfentanil 10 microg.kg-1, thiopentone 5 mg.kg-1 and the study drug. Intubation was attempted at 30 s after injection of neuromuscular relaxant and intubating conditions graded as excellent, good, poor or impossible. RESULTS: All 120 children were successfully intubated within 60 s without need for a second attempt after administration of neuromuscular relaxant. Differences between suxamethonium and rocuronium 0.6 mg.kg-1 and between the two doses of rocuronium were statistically significant (P=0.016 and 0.007, respectively). CONCLUSIONS: Rocuronium 0.9 mg.kg-1 provides similar intubating conditions to suxamethonium 1.5 mg.kg-1 during modified rapid-sequence induction using alfentanil and thiopentone in children (P=0.671). Rocuronium 0.6 mg.kg-1 was inadequate. 相似文献

We determined the effective time to satisfactory intubation conditions after the administration of rocuronium 0.6 mg.kg-1 to 120 unpremedicated adult patients anaesthetised with propofol 2.5 mg.kg-1 or thiopentone 5 mg.kg-1. Intubation conditions were assessed in 10 subgroups of 12 patients at 30, 40, 50, 60 and 70 s. The effective times to satisfactory intubation conditions in 50 and 90% of patients were obtained by the method of maximum likelihood after log time-probit response transformations. Intubation conditions after induction of anaesthesia with propofol were satisfactory in 5/12 patients at 30 s, 7/12 at 40 s, 10/12 at 50 s, 11/12 at 60 s and 11/12 at 70 s compared with 1/12 patients at 30 s, 2/12 at 40 s, 5/12 at 50 s, 7/12 at 60 s and 8/12 at 70 s after induction with thiopentone. The effective times to satisfactory intubation conditions in 50% and 90% (95% confidence intervals) of patients after rocuronium 0.6 mg.kg-1 were 34 (26-40) s and 61 (50-81) s in patients given propofol compared with 57 (48-69) s and 101 (79-167) s in patients given thiopentone. We conclude that rocuronium 0.6 mg.kg-1 may be a suitable alternative to suxamethonium during rapid sequence induction of anaesthesia with propofol in situations where suxamethonium is contraindicated. 相似文献
