Objectives: This study was conducted to investigate the association between visible cardiac activity in point-of-care ultrasound (POCUS) and outcomes of cardiac arrest such as the return of spontaneous circulation (ROSC), survival to inpatient admission (SIA), and survival to hospital discharge (STHD).
Methods: This was a single-center, prospective cohort study conducted in the emergency department (ED). Adult (age >18 years) patients in cardiac arrest were included in the study. Exclusion criteria of the study were - traumatic arrest, out-of-hospital cardiac arrest resuscitated before ED admission, and patients presenting with initial shockable rhythm. Patients whose ultrasound images could not be obtained and whose resuscitation stopped following POCUS were also excluded from the study. POCUS examination was done after 2 min of initiation of cardiopulmonary resuscitation (CPR) and visible cardiac activity was defined as any visible movement of the myocardium, excluding movement of blood within cardiac chambers, or isolated valve movement. The duration of POCUS examinations was limited to 10 s. The association of initial cardiac activity in POCUS with the outcomes of cardiac arrest was investigated.
Results: Out of 140 patients screened, 84 patients were included in the study. Rates of ROSC, SIA, and STHD were found in 23 (27.4%), 9 (10.7%), and 2 (2.4%) patients, respectively. Only 15 out of 84 (17.9%) patients had cardiac activity on the initial POCUS examination. Cardiac activity was seen in 52.2% of patients with ROSC, which was significantly higher (P < 0.001) as compared with the no-ROSC group (4.9%). Unlike the above association, there was no difference in the incidence of initial cardiac activity in patient groups who got admitted (SIA) and discharged (STHD) versus those who died. In the multivariate regression analysis, the duration of CPR and initial cardiac activity significantly predicted the rate of ROSC, with an adjusted odds ratio of 0.93 (95% confidence interval [CI]: 0.86-0.99, P = 0.04) and 24.8 (95% CI: 3.17-89.41, P = 0.002), respectively. None of the variables predicted SIA and STHD. The positive likelihood ratio of cardiac activity for predicting ROSC, SIA, and STHD were 10.6, 2.1, and 2.9, respectively.
Conclusion: Integration of POCUS in cardiac arrest resuscitation was shown to be helpful in terms of prognostic significance of the presence of initial cardiac activity in terms of ROSC.
We present a patient with multiple bee stings who developed lung and liver injuries and subsequently tested positive for coronavirus disease 2019 (COVID-19). A 65-year-old male patient presented to the emergency department after being stung by more than 100 honeybees. His physical examination revealed pustular lesions distributed across his chest, arms, back, legs, and head, marking the sting zones. While the patient had no history of liver disease, initial laboratory test results showed elevated liver enzyme levels. A chest computer tomography scan was ordered, revealing bilateral ground-glass opacities suggesting COVID-19. His condition worsened over the course of the following day, and when he was admitted to the intensive care unit (ICU), his SpO2 decreased to 83% despite oxygen support with a mask. The second polymerase chain reaction test taken in the ICU was positive for COVID-19 infection. After stung with multiple bees, the patient developed acute liver injury and suffered from concomitant COVID-19-related respiratory insufficency, and he was treated accordingly. Starting on the 5th day, the patient's liver markers began to improve, and on the 13th day, he was discharged with normal vital signs and liver enzyme values. There seem to be varying outcomes across different studies with regard to the relationship between bee stings and COVID-19. Further research is needed to explore the possibility of this complementary treatment with bee venom in the prevention of severe acute respiratory syndrome coronavirus-2 infection.
Objectives: Various ultrasound (US)-guided probe positioning and needle procedures have been described in the literature for cannulation of the internal jugular vein (IJV). In the present study, we compared the conventional short-axis out-of-plane (SAX-OOP) method with a novel anteroposterior short-axis in-plane (APSAX-IP) technique for IJV cannulation under US guidance. The APSAX-IP method of IJV cannulation has not been compared to other IJV cannulation techniques.
Methods: A total of 104 patients above 18-year-old were randomly allocated to one of two groups - APSAX-IP or SAX-OOP and evaluated for US-guided IJV cannulation in either the operating room or critical care unit. The primary outcome of this research was the access time for IJV cannulation using both approaches. The secondary outcomes were the number of attempts of needle insertion, success rate, and complications of IJV cannulation.
Results: The access time for IJV cannulation was 13.0 (12.0-15.0) sec in the APSAX-IP group and 13.0 (12.0-14.0) sec in the SAX-OOP group; P = 0.947. The number of successful 1st attempts was 90.91%, and the 2nd attempts were 9.09% in the APSAX-IP group and 85.19% and 14.81% in the SAX-OOP group, respectively. Both techniques did not have any complications.
Conclusions: We conclude that the US-guided APSAX-IP IJV cannulation method has comparable access time to the SAX-OOP technique.
Objectives: This single-center, retrospective study investigates the predictive value of cardiovascular (CV) risk-calculation systems in patients admitted to the emergency department with carbon monoxide (CO) intoxication for the identification of potential myocardial injury.
Methods: The total CV risk of 558 patients presenting to the emergency department with CO intoxication were calculated on admission using different CV risk scoring systems, including SCORE Turkey, European Heart SCORE, and FRAMINGHAM to predict potential myocardial injury secondary to poisoning, and the risk levels were categorized based on the calculated scores. The presence of myocardial injury was identified based on the level of elevation of a cardiac biomarker (Serum cardiac troponin-I >99th percentile upper reference limit).
Results: Myocardial injury due to CO intoxication was detected in 132 (23.7%) of the patients. A comparison of the risk scoring systems' ability to detect the presence of myocardial injury revealed that all had significant, similar, but low predictive values (the "area under the curve" values of SCORE Turkey, European Heart SCORE and FRAMINGHAM were 0.653, 0.632, and 0.629, respectively; P < 0.001). Among the three risk scoring systems, SCORE Turkey was the most successful test in diagnosing myocardial injury with 87% specificity, while FRAMINGHAM scoring was the most successful test in excluding the presence of myocardial injury with 72.1% sensitivity.
Conclusion: Among the tested CV risk-calculation systems SCORE Turkey, was found to be the most effective in the prediction of myocardial injury secondary to CO poisoning, but all produced similar and significant results.
Objectives: Evaluating local trends and continued monitoring of patterns of acute poisoning are essential for prompt recognition of the toxidromes, the establishment of immediate treatment facilities (e.g., antidote availability), and effective preventive strategies (e.g., governmental regulation on hazardous substances marketing). We aimed to describe the prevalence of the various types of poisoning and associated case fatality in our academic hospital in North India.
Methods: A prospective observational descriptive study was conducted, enrolling patients aged ≥13 years with acute poisoning for 17 months from December 2016 to December 2017 and from September 2019 to December 2019, for a total of 17 months.
Results: Four hundred and two patients were enrolled (median age 28 years; 63.2% males). Majority of the acute poisoning cases resulted from ingestion (n = 391, 97.3%) and the primary intention was most commonly self-harm (n = 314, 78.1%). The major types of poisoning were pesticide (n = 264, 65.7%), drug overdose (n = 77, 19.2%), and corrosive ingestion (n = 31, 7.7%). Pesticides included insecticides (n = 146, 36.3%; cholinesterase inhibitors, n = 91), fungicides (n = 76, 18.9%; all aluminum phosphide), herbicides (n = 22, 5.5%; paraquat, n = 19), and rodenticides (n = 20, 5.0%; coumarin-derived substances, n = 12). Benzodiazepines (n = 33) and opioids (n = 25) were frequent causes of drug overdose. 95.3% (n = 379) received preliminary treatment at the previous health-care center, including gastric lavage (n = 239) and antidotes (n = 73). In-hospital case fatality rate was 17.3% (n = 58).
Conclusion: Herbicide ingestion and opioid overdose are emerging threats with a gradual decline in organophosphate and aluminum phosphide poisoning. Despite improving management of acute poisoning, the overall case fatality rate remains substantial.
