TEA provided superior anaesthesia compared to PCA in our study group. Use of PCA oxycodone in postoperative pain management after open thoracotomy provides similar nociception control compared to morphine but is associated with less sedation and patients using oxycodone IVPCA require smaller doses of rescue analgesia compared to systemic morphine IVPCA.
Pentobarbital is the most suitable anesthetic offering stable hemodynamic values during arrhythmia studies. These hemodynamic values, which were similar to physiological values in awake rats, the long arrhythmia duration during reperfusion and approximately 50% mortality index are crucial parameters for evaluating antiarrhythmic drugs.
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.
BackgroundPredicting difficult intubation is of high clinical interest.Methods237 patients aged ≥18 years were included in the study. Preoperative airway evaluation included: Mallampati test, thyromental distance, sternomental distance and thyromental height test. During direct laryngoscopy Cormack & Lehane classification was graded. We calculated the ROC AUC, sensitivity and specificity for thyromental height test as a primary end point of our study.ResultsOnly thyromental height test and Cormack-Lehane scale proved significant on occurrence of difficult intubation. The optimal sensitivity and specificity values of thyromental height test were met with a cut off value of 50 mm. With 1 mm increase in thyromental height test, risk of difficult intubation decreased by 7%.ConclusionThyromental height test is a simple, easy to perform and non-invasive test to predict difficult intubation in patients scheduled for elective double lumen tube intubation during thoracic surgical procedures. With 1 mm above 50 mm increase in thyromental height test the risk of difficult intubation decreased by 7%.Trial registrationClinicaltrials.gov Identifier: NCT02988336.
INTRODUCTION:During a pandemic, medical personnel while in contact with patients with suspected/confirmed COVID-19 should wear full personal protective equipment (PPE) for aerosol-generating procedures to reduce the risk of infection. Most studies of intubation in level C PPE conditions have been relatively small. Our aim is to quantify the available data on success rates in order to provide an evidence-based benchmark to gauge performance in the published literature.
MATERIAL AND METHODS:A structured literature search was performed with PubMed, Scopus, Embase, Web of Science, and Cochrane databases. The electronic database search was supplemented by searching Google Scholar and by back-searching the reference lists of identified studies for suitable articles. Data were evaluated and extracted by two independent reviewers on the basis of qualitative and quantitative variables of interest. Q statistic and I 2 statistics were used to assess the heterogeneity between the studies.
RESULTS:Fifteen randomized controlled trials were included. The use of PPE during intubation as compared with intubation without PPE reduced intubation efficacy (90.0% vs. 97.9%; RR = 0.94; 95% CI: 0.90-0.99; p < 0.001) and increased the procedure time (MD = 7.73; 95%
