Difficult Airways

Introduction. Airway management is one of key elements of resuscitation. Endotracheal intubation is still considered the gold standard for airway management during resuscitation. Aim. The aim of the study was to compare success rates and intubation time of different endotracheal intubation methods during emergency intubation with difficult airways in the conditions of cardiopulmonary resuscitation in a standardized manikin model. Methods. The study was designed as a prospective, randomized, cross-over simulation study. It involved 46 paramedics with at least 5 years of experience in Emergency Medical Service. The participants performed endotracheal intubation under difficult airway conditions during continuous chest compression, implemented with the LUCAS3 chest compression system. Three methods of tracheal intubation were applied: (1) standard Macintosh laryngoscope without a bougie stylet; (2) standard laryngoscope and a standard bougie stylet; (3) standard laryngoscope and a new bougie stylet. Results. The overall intubation success rate was 100% in the standard bougie and new bougie groups and lower (86.9%) when no bougie stylet was used (P=0.028). The intubation success rate with the 1st attempt equalled 91.3% for the new bougie group, 73.9% for standard bougie, and only 23.9% in the no-bougie group. The median intubation time was shortest in the new bougie group, where it amounted to 29 s (interquartile range [IQR]: 25–38); the time equalled 38s (IQR:31–44.5) in the standard bougie group and 47.5s (IQR:36–58) in the no-bougie group. The ease of use was lowest in the no-bougie group (85, IQR:63–88), average in the standard bougie group (44, IQR:30–51), and highest in the new bougie stylet group (32, IQR:19–41). Conclusion. In this manikin-based study, paramedics were able to perform endotracheal intubation with higher efficacy and in a shorter time using the new bougie stylet as compared with the standard bougie stylet.

Spine Movement

Background In the emergency trauma situation, in-line stabilization (ILS) of the cervical spine is used to reduce head and neck extension during laryngoscopy. The Bullard laryngoscope may result in less cervical spine movement than the Macintosh laryngoscope. The aim of this study was to compare cervical spine extension (measured radiographically) and time to intubation with the Bullard and Macintosh laryngoscopes during a simulated emergency with cervical spine precautions taken. Methods Twenty-nine patients requiring general anesthesia and endotracheal intubation were studied. Patients were placed on a rigid board and anesthesia was induced. Laryngoscopy was performed on four occasions: with the Bullard and Macintosh laryngoscopes both with and without manual ILS. Cricoid pressure was applied with ILS. To determine cervical spine extension, radiographs were exposed before and during laryngoscopy. Times to intubation and grade view of the larynx were also compared. Results Cervical spine extension (occiput-C5) was greatest with the Macintosh laryngoscope (25.9 degrees +/- 2.8 degrees). Extension was reduced when using the Macintosh laryngoscope with ILS (12.9 +/- 2.1 degrees) and the Bullard laryngoscope without stabilization (12.6 +/- 1.8 degrees; P < 0.05). Times to intubation were similar for the Macintosh laryngoscope with ILS (20.3 +/- 12.8 s) and for the Bullard without ILS (25.6 +/- 10.4 s). Manual ILS with the Bullard laryngoscope results in further reduction in cervical spine extension (5.6 +/- 1.5 degrees) but prolongs time to intubation (40.3 +/- 19.5 s; P < 0.05). Conclusions Cervical spine extension and time to intubation are similar for the Macintosh laryngoscope with ILS and the Bullard laryngoscope without ILS. However, time to intubation is significantly prolonged when the Bullard laryngoscope is used in a simulated emergency with cervical spine precautions taken. This suggests that the Bullard laryngoscope may be a useful adjunct to intubation of patients with potential cervical spine injury when time to intubation is not critical.

AbstractThe purpose of this study was to measure the contributions of a physician crew member in a helicopter emergency medical service (HEMS) and to develop a method to utilize physician services more efficiently. A two-part study utilizing two independent sets of measurements of physician necessity was conducted. A post-flight questionnaire and the success rate for endotracheal intubation were used as measurement tools.With the passage of time, the fight nurses perceived the physician crew member' contribution to clinical judgment decreased from 21% to 1% of the flights and that the physician's contribution of technical skills (intubation) declined from 11% to 3%. The contribution to clinical decisions seemed more important on interhospital transports than on scene responses. The technical skills (judged by the tracheal intubation success rates) of a physician seemed more cogent on responses to the scene. When in the capacity of a second crew member with an experienced flight nurse, the endotracheal intubation success rate increased from 71% to 90%. Therefore, it seems that physician services could be restricted primarily to scene response flights. This limited utilization of flight physicians should make these physicians available for other duties.

Purpose. This study aimed to compare intubation performances among i-gel blind intubation (IGI), i-gel bronchoscopic intubation (IBRI), and intubation using Macintosh laryngoscope (MCL) applying two kinds of endotracheal tube during chest compressions. We hypothesized that IGI using wire-reinforced silicone (WRS) tube could achieve endotracheal intubation most rapidly and successfully. Methods. In 23 emergency physicians, a prospective randomized crossover manikin study was conducted to examine the three intubation techniques using two kinds of endotracheal tubes. The primary outcome was the intubation time. The secondary outcome was the cumulative success rate for each intubation technique. A significant difference was considered when identifying p<0.05 between two devices or p<0.017 in post hoc analysis of the comparison among three devices. Results. The mean intubation time using IGI was shorter (p<0.017) than that of using IBRI and MCL in both endotracheal tubes (17.6 vs. 29.3 vs. 20.2 in conventional polyvinyl chloride (PVC) tube; 14.6 vs. 27.4 vs. 19.9 in WRS tube; sec). There were no significant (p<0.05) differences between PVC and WRS tubes for each intubation technique. The intubation time to reach 100% cumulative success rate was also shorter in IGI (p<0.017) than that in IBRI and MCL in both PVC and WRS tubes. Conclusions. IGI was an equally successful and faster technique compared with IBRI or MCL regardless of the use of PVC or WRS tube. IGI might be an appropriate technique for emergent intubation by experienced intubators during chest compressions.
