Comparison of rocuronium priming vs. standard rapid sequence intubation technique in emergency department patients requiring intubation.

OBJECTIVE: In our study, we aimed to compare the effect of standard rapid sequence intubation protocol and the application of rocuronium priming technique on the procedure time and hemodynamic profile. METHODS: Patients who applied to the emergency department and needed rapid sequence intubation were included in our study, which we conducted with a randomized controlled design. Randomization in the study was made according to the order of arrival of the cases. Rapid sequence intubation was performed in the standard group. In the priming group, 10% of the rocuronium dose was administered approximately 3 min before the induction agent. Intubation time, amount of drug used, vital signs, and end-tidal CO2 level before and after intubation used to confirm intubation were recorded. RESULTS: A total of 52 patients were included in the study, of which 26 patients were included in the standard group and 26 patients in the priming group. While intubation time was 121.2±21.9 s in the standard group, it was calculated as 68.4±11.6 s in the priming group (p<0.001). While the mean arterial pressure was 58.3±26.6 mmHg in the standard group after intubation, it was 80.6±21.1 mmHg in the priming group (p=0.002). CONCLUSION: It was observed that priming with rocuronium shortened the intubation time and preserved the hemodynamic profile better. CLINICAL TRIAL REGISTRATION NUMBER: NCT05343702.

Manual versus mechanical chest compression in in-hospital cardiac arrest: A retrospective cohort in emergency department patients.

OBJECTIVE: Mechanical chest compression (CC) devices are frequently used in in-hospital and out-of-hospital settings. In this study, mechanical and manual CC in in-hospital cardiac arrest was compared in terms of survival. METHODS: Adult patients who were admitted to the emergency department (ED) for 2 years period and had cardiac arrest in the ED were included in this retrospective, observational study. Return of spontaneous circulation (ROSC), 7-day and 30-day survival and hospital discharge data were compared between the two groups of patients who underwent manual CC and those who had mechanical CC with the Lund University Cardiac Assist System-2 device. RESULTS: Although the rate of ROSC in the mechanical CC group was lower than in the manual CC group, this difference was not statistically significant (41.7% vs. 50.4%; P = 0.133). The 7-day survival rate was found to be statistically significantly higher in the mechanical CC group (19.4% vs. 8.9%; P = 0.012). The 30-day survival rate was also found to be high in the mechanical CC group, but this difference was not statistically significant (10.6% vs. 7.3%; P = 0.339). CONCLUSION: In the light of these results, we can say that the use of piston-based mechanical CC devices in ED may be beneficial. More reliable results can be obtained with a prospective study to be performed in the ED.

Assessment of SARS-CoV-2 in the Cerumen of COVID-19-Positive Patients.

OBJECTIVE: To evaluate the presence of SARS-CoV-2 virus in the cerumen of patients with COVID-19. METHODS: A prospective study was conducted in a tertiary care pandemic hospital. Sixty COVID-19 patients with cerumen in their external auditory canals were included in the study. Swabs were taken from the external auditory canal of the patients by an experienced otolaryngologist with the test swab. Sampling was done by rotating the sample swab 360° 10 times in each external auditory canal for a total of 20 times. After collection, swabs were placed into 2 mL of the sterile viral transport medium (various manufacturers), then transported and tested as soon as possible after collection. RESULTS: SARS-CoV-2 was not detected in the cerumen polymerase chain reaction (PCR) samples of any of the 60 patients with positive nasopharyngeal/oropharyngeal swabs. CONCLUSION: Cerumen cleaning is one of the most common procedures performed by otolaryngologists, and care should be taken during the procedure or due to the possibility of infection from the resulting contaminants. The cerumen contains the secretions of the glands in the external auditory canal and may contain certain pathogens that are actively found in the body. The presence of hepatitis B virus in the cerumen was examined and isolated in the cerumen. In our study, the presence of SARS-CoV-2 virus in the cerumen was evaluated in SARS-CoV-2 PCR-positive patients. SARS-CoV-2 virus was not detected in the cerumen samples of any of the patients.

Evaluation of oxidative stress tests in patients diagnosed with renal colic in the emergency department of Ankara Ataturk Training and Research Hospital, Turkey.

OBJECTIVE: To investigated oxidative stress changes in renal colic patients, and to determine its role in differential diagnosis of renal colic. METHODS: The cross-sectional study was conducted at Ankara Atatürk Training and Research Hospital, Turkey, from June 2012 to December 2012 and comprised patients with complaints suggesting of renal colic and diagnosed with urinary stone. Healthy individuals were enrolled to form the control group. The patients and the control group were evaluated in terms of oxidative stress parameters. SPSS 17 was used for statistical analysis. RESULTS: Of the 83 subjects, 50(60%) were patients with renal colic, while 33(40%) were healthy controls. Among the patients, 25(50%) were men and 25(50%) were women. Among the controls, there were 17(51.5%) men and 16(48.5%) women. No statistically significant difference was found between the two groups in terms of age and gender (p>0.05). Likewise, no statistically significant difference was found between the oxidative stress indexes of the two groups (p>0.05). CONCLUSIONS: There was no significant increase in oxidative stress in patients with renal colic. The result may help in the differential diagnosis of patients with abdominal pain.

Evaluation of residents' thoughts about giving the news of death.

OBJECTIVE: To assess behaviours and attitudes of residents toward giving news of death in emergency department and other departments. METHODS: The study was conducted between 1st and 7th December, 2012, in an urban hospital in Ankara, Turkey. It used a questionnarie that was filled by 100 residents from different disciplines of medicine. Categorical variables were analysed with Chi-square and Fisher's exact tests and continuous variables were analysed with Mann Whitney test. The level of statistical significance was set at 0.05. RESULTS: The most difficult cases to notify were those of unexpected and sudden deaths (n = 51; 51%) followed by deaths of children (n = 36; 36%). While 60% (n = 60) of the study group reported a need for training in this area, but there was no association between having difficulty in notifying a death and expressing the need for training (p = 0.187). Residents who had difficulty in notifying death informed the patient's close ones more often during resuscitation (p = 0.049) and requested for security staff more often during the final briefing compared with the group that did not express having difficulty (p < 0.001). CONCLUSION: Notifying death is still a challenging issue in medicine. Instead of educational efforts, security measures may be more beneficial and comforting for residents who have difficulty in conveying the news.

The accuracy of mainstream end-tidal carbon dioxide levels to predict the severity of chronic obstructive pulmonary disease exacerbations presented to the ED.

INTRODUCTION: The end-tidal carbon dioxide (ETCO2) measurement was considered as an essential tool for the assessment of several conditions in emergency medicine. However, the diagnostic role of capnography in dyspneic patients still remains unclear. We aimed to analyze the alteration of the ETCO2 levels in chronic obstructive pulmonary disease (COPD) exacerbations and its role in the decision-making process. METHODS: All the individuals who were presented to the emergency department (ED) after COPD exacerbations were prospectively enrolled in the study. The patients were excluded if they refused to give informed consent, intubated after initial assessment, and had uncertain COPD diagnosis. The ETCO2 measurement using a mainstream capnometer was undertaken in the pretreatment and post-treatment period of COPD exacerbations. RESULTS: A total of 102 patients were enrolled in the study. Pre-ETCO2 and post-ETCO2 levels were positively correlated with arterial partial carbon dioxide pressure levels (r=0.756, P<.001 and r=0.629, P<.001, respectively). The median pre-ETCO2 level was 32.0 (30.5-40.5) in discharged patients and 39.0 (31.0-53.5) in admitted patients. After the initial therapy in the ED was completed, the median post-ETCO2 level was found to be 32.0 (28.0-37.5) in discharged patients and 36.0 (32.0-52.0) in admitted patients. Although a statistically significant difference was observed in the pretreatment period (P=.043), no difference was observed in post-treatment period between ETCO2 levels (P=.107). CONCLUSION: End-tidal carbon dioxide levels were higher in admitted patients when compared with discharged patients on arrival to the ED. ETCO2 measurement has very little contributions while evaluating patients with COPD exacerbation in the ED.

Determining the diagnostic value of endogenous carbon monoxide in chronic obstructive pulmonary disease exacerbations.

OBJECTIVE: To determine whether endogenous carbon monoxide levels in exacerbations of Chronic Obstructive Pulmonary Disease patients were higher compared to healthy individuals and to investigate alteration of carbon monoxide levels across the three different severity stages of Global Initiative for Chronic Obstructive Lung Disease criteria related to Chronic Obstructive Pulmonary Disease exacerbations. METHODS: The prospective study was conducted from January to March 2011 at two medical institutions in Ankara, Turkey, and comprised patients of acute Chronic Obstructive Pulmonary Disease exacerbations. The severity of the exacerbations was based on the Global Initiative for Chronic Obstructive Lung Disease criteria. Patients with active tobacco smoking, suspicious carbon monoxide poisoning and uncertain diagnosis were excluded. healthy control subjects who did not have any comorbid diseases and smoking habitus were also enrolled to compare the differences between carboxyhaemoglobin levels A two-tailed Mann-Whitney U test with Bonferroni correction was done following a Kruskal-Wallis test for statistical purposes. RESULTS: There were 90 patients and 81 controls in the study. Carboxyhaemoglobin levels were higher in the patients than the controls (p < 0.001). As for the three severity stages, Group 1 had a median carboxyhaemoglobin of 1.6 (0.95- 2.00). The corresponding levels in Group 2 (1.8 [1.38-2.20]) and Group 3 (1.9 [1.5-3.0]) were higher than the controls (p < 0.001 and p < 0.005 respectively). No statistically significant difference between Group 1 and the controls (1.30 [1.10-1.55]) was observed (p < 0.434). CONCLUSION: Carboxyhaemoglobin levels were significantly higher in exacerbations compared with the normal population. Also, in more serious exacerbations, carboxyhaemoglobin levels were significantly increased compared with healthy individuals and mild exacerbations.
