Comparison of carotid artery ultrasound and manual method for pulse check in cardiopulmonary resuscitation.

OBJECTIVES: The success of the manual pulse check method frequently employed during cardiopulmonary resuscitation (CPR) is controversial due to its subjective, patient- and operator-dependent, and time-consuming nature. Carotid ultrasound (c-USG) has recently emerged as an alternative, although there are still insufficient studies on the subject. The purpose of the present study was to compare the success of the manual and c-USG pulse check methods during CPR. METHODS: This prospective observational study was conducted in the critical care area of a university hospital emergency medicine clinic. Pulse checks in patients with non-traumatic cardiopulmonary arrest (CPA) undergoing CPR were performed using the c-USG method from one carotid artery and the manual method from the other. The gold standard in the decision regarding return of spontaneous circulation (ROSC) was the clinical judgment made using the rhythm on the monitor, manual femoral pulse check, end tidal carbon dioxide (ETCO2), and cardiac USG instruments. The success in predicting ROSC and measurement times of the manual and c-USG methods were compared. The success of both methods was calculated as sensitivity and specificity, and the clinical significance of the difference between the methods' sensitivity and specificity was evaluated Newcombe's method. RESULTS: A total of 568 pulse measurements were performed on 49 CPA cases using both c-USG and the manual method. The manual method exhibited 80% sensitivity and 91% specificity in predicting ROSC (+PV: 35%, -PV: 64%), while c-USG exhibited 100% sensitivity and 98% specificity (+PV: 84%, -PV: 100%). The difference in sensitivities between the c-USG and manual methods was -0.0704 (95% CI: -0.0965; -0.0466), and the difference between their specificities was 0.0106 (95% CI: 0.0006; 0.0222). The difference between the specificities and sensitivities was statistically significant at analysis performed adopting the clinical judgment of the team leader using multiple instruments as the gold standard. The manual method yielded an ROSC decision in 3 ± 0.17 s and c-USG in 2.8 ± 0.15 s, the difference being statistically significant. CONCLUSION: According to the results of this study, the pulse check method with c-USG may be superior to the manual method in terms of fast and accurate decision making in CPR.

The value of conventional manometry in the identification of normal esophageal manometry.

ABSTRACT: In the last decade, high-resolution esophageal manometry (HREM) is the main device for the management of dysphagia replacing conventional manometry (CM). Conventional manometry still seems to have some space to diagnose major motility disorders and differentiate normal from abnormal esophageal motility. The long term outcomes of patients with normal CM were analyzed in our study.Participants (patients with dysphagia and normal CM) took a questionnaire via a phone call in February 2021. Impact Dysphagia Questionnaire (IDQ) was used as an assessment tool.Only 55% (83/151) the individuals with previous normal manometric findings were reached via telephone. The group who have completed the survey was representative of the cohort. 66.2% of the participants were female (P = .40). The mean age was 57.21, mean weight was 70.69 kg, mean height was 163.74 cm and mean body mass index was 26.41. More than 40% of patients were completely asymptomatic at follow up, reflected by an IDQ score of 0. Only 28 out of 83 (33.7%) patients reported significant symptoms as reflected by an IDQ score greater than or equal to 7. The rest of responders admitted as having moderate to mild symptoms.HREM is a valid technique with comparable precision to CM. HREM measurements differ considerably to CM. The identification of normal motor function in CM is not likely a positive prognostic indicator and must be interpreted precautiously.

A rare complication of continuous positive airway pressure treatment - rectus sheath hematoma: a case report.

Noninvasive mechanical ventilation (NIMV) has a relevant role in the treatment of critically ill patients displaying severe dyspnea. Continuous positive airway pressure (CPAP), a method of NIMV, is also widely used in the management of acute heart failure, chronic obstructive pulmonary disease (COPD) exacerbation, and symptomatic sleep apnea. However, numerous traumatic complications of CPAP treatment in the face region, head, and thorax have been reported and may be related to the application of a continuous positive high pressure to the airway. Conversely, we have observed no complications due to CPAP-related increased intra-abdominal pressure. In this article, we describe a clinical case of a patient with an acute rectus sheath hematoma during CPAP treatment. This previously unreported complication demonstrates that CPAP should be carefully used in patients with exacerbated COPD with difficulty in expiration.

When is the right time to take an emergency surgery decision in Mechanical Intestinal Obstruction?

BACKGROUND: /Objective: Ischemia is a leading cause of morbidity in Mechanical Intestinal Obstruction (MIO) in which the timing of decisions of whether to proceed to surgical or conservative treatment is critical in emergency departments (ED). While advanced technological options are available, patients may be negatively affected by the application of contrast agents or radiation. The use of ultrasound is limited because of the air in the intestines does not allow a good field of vision. While biomarkers can be considered as a good alternative option at this point. In the present study we examine the effect of hemogram and blood gas parameters on early surgical decision-making in MIO patients. METHOD: Involved in this observational prospective study were 264 patients diagnosed with MIO who presented to the Department of Emergency Medicine, Ataturk Research and Training Hospital, Katip Celebi University between February 2018 and February 2019. Contrast-enhanced tomography (CECT) and laboratory results of the patients were recorded. Pathology reports of the patients who underwent surgery were collected. Laboratory data were analyzed by comparing CECT and pathology reports. RESULTS: In a ROC analysis of the laboratory values of the patients who were diagnosed with ileus, the sensitivity was calculated as 80% and the specificity was 57.7 in values above WBC>10.75 (109/L), 96.6%, and the specificity was 31.1% in N/L > 2.9. For intestinal ischemia, the cut-off values were WBC> 12.6 and N/L > 3.2, Lactate >2.8 mmol/L and B.E < -3.6 mmol/L. CONCLUSION: Diagnoses of ileus are based on the results examinations and imaging methods. More data are needed to support decisions on the timing of surgery in ED. WBC, N/L, Lactate and Base Excess indicate an ischemic segment. When the parameters are evaluated together, they strongly support early surgical decision-making regarding the treatment of intestinal ischemia.

A Rare Ultrasonographic Finding of Emphysematous Cholecystitis: The Champagne Sign.

BACKGROUND: Emphysematous cholecystitis (EC) is a form of cholecystitis with high mortality rates more commonly seen in patients with medical histories such as diabetes, hypertension, and peripheral vascular disease. The common features of these medical diseases are impaired pain perception, particularly abdominal pain, due to advanced age and peripheral neuropathies. Accurate evaluation of characteristics observed at ultrasonography, the method of first choice in the diagnosis of EC, is therefore highly important in these patients. CASE REPORT: This study reports a case of the champagne sign, rarely seen in EC, together with other EC findings. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The champagne sign is a little-known sonographic finding that is evidence of the presence of gas in the gallbladder. The champagne sign that will be detected while evaluating the hepatobiliary system on bedside ultrasound is one of the valuable findings in the diagnosis of emphysematous cholecystitis with high mortality.

The Feasibility of the Ultrasound-Guided Femoral Nerve Block Procedure with Low-Dose Local Anesthetic in Intracapsular and Extracapsular Hip Fractures.

BACKGROUND: The local anesthetic dosages used in the current literature in regional applications of local anesthetics are frequently high for surgical purposes, and there are no sufficient dosage studies for emergency department (ED) management. OBJECTIVES: The aim of this study was to determine the success of lower local anesthetic dosages capable of reducing costs and excessive exposure to drugs in pain control in patients with femoral neck fractures (FNFs) in the ED. METHODS: Patients ≥65 years of age with FNFs and reporting Wong-Baker Pain Rating Scales scores ≥8 were included in this prospective, interventional study. Patients underwent ultrasound-guided regional femoral block with 5 mL 2% prilocaine. Pain scores before the procedure and at 30 min and 2 h postprocedure were compared with the Friedman test and Wilcoxon test with Bonferroni correction. RESULTS: Forty patients, 20 with intracapsular and 20 with extracapsular FNFs, were enrolled. The initial pain scores of patients with both intra- and extracapsular fractures were 8 (range 8-10). A statistically significant 50% decrease in pain scores was observed in both groups 30 min after the regional block procedure (p < 0.001). A statistically significant 75% decrease in pain scores was observed in both groups 2 h after the regional block procedure (p < 0.001). No statistically significant difference was determined in the change in 30-min and 2-h pain scores between the groups. CONCLUSIONS: The administration of 5 mL 2% prilocaine for pain control in FNFs in elderly patients in the ED can reduce systemic analgesic requirements by establishing effective analgesia in both intracapsular and extracapsular fractures.

Effect of Changes in Intravascular Volume on Inferior Vena Cava and Aorta Diameters and the Caval/Aorta Index in Healthy Volunteers.

OBJECTIVES: Although inferior vena cava diameter (IVCD) measurement can be useful as a noninvasive method for monitoring the volume status, the benefit of abdominal aorta diameter (AAD) measurement is unclear. The purpose of this study was to determine the value of the combined use of the IVCD and AAD in blood loss monitoring. METHODS: This prospective observational study was conducted at the blood donor center of a training and research hospital. Standard blood donation criteria were followed during volunteer enrollment. Vital signs and ultrasound IVCD and AAD measurements were obtained before and after blood donation and after fluid resuscitation with 500 mL of 0.9% sodium chloride. Measurements before and after blood donation and after fluid resuscitation were compared by the paired t and Wilcoxon matched-pair tests. RESULTS: Thirty-nine volunteers were included in the study. With 500 mL of blood loss, percent changes in the shock index (SI; mean ± SD, 7% ± 6%), IVCD (6% ± 2%), and caval/aorta index (IVCD/AAD; 6.1% ± 3%) were similar and were higher (P < .001 for all parameters) than the changes in the pulse rate (3% ± 4%), AAD (0.5% ± 1.5%), systolic blood pressure (3% ± 4%), and diastolic blood pressure (2% ± 7%). Although IVCD and SI values changed significantly (P < .001 for both) after 500 mL of 0.9% sodium chloride resuscitation, no significant change was observed in the IVCD/AAD (P = .059). CONCLUSIONS: The IVCD/AAD, SI, and IVCD may have similar success rates in diagnosing early blood loss. Additionally, the SI and IVCD may be superior to the IVCD/AAD in bleeding patients requiring simultaneous fluid resuscitation.

Application of scoring systems with point-of-care ultrasonography for bedside diagnosis of appendicitis.

BACKGROUND: Appendicitis is a common disease requiring surgery. Bedside ultrasound (BUS) is a core technique for emergency medicine (EM). The Alvarado score is a well-studied diagnostic tool for appendicitis. This study aimed to investigate the relationship between patients' symptoms, Alvarado score and ultrasound (US) findings, as performed by emergency physicians (EPs) and radiologists, of patients with suspected appendicitis. METHODS: Three EM specialists underwent the BUS course and core course for appendicitis assessment. Patients suspected of having appendicitis were selected and their Alvarado and modified (m) Alvarado scores calculated. The specialists performed the BUS. Then, patients were given a formal US and surgery consultation if necessary. Preliminary diagnoses, admission or discharge from the emergency department (ED) and final diagnosis were documented. The patients were also followed up after discharge from the hospital. RESULTS: The determined cut-off value was 2 for Alvarado and 3 for mAlvarado scores. The sensitivities of the two scores were 100%. Each score was used to rule out appendicitis. The results of EP-performed BUS were as follows: accuracy 70%, sensitivity 0.733, specificity 0.673, + LR 2.24, and - LR 0.40 (95%CI). Radiologists were better than EPs at diagnosing appendicitis and radiologists and EPs were equally strong at ruling out appendicitis by US. When US was combined with Alvarado and mAlvarado scores, EP US+Alvarado/mAlvarado scores <3 and radiology US+Alvarado/mAlvarado scores <4 perfectly ruled out appendicitis. CONCLUSION: BUS performed by EPs is moderately useful in detecting appendicitis. Combined with scoring systems, BUS may be a perfect tool for ruling out decisions in EDs.

A deadly complication of superficial muscular needle electromyography: bilateral pneumothoraces.

Needle electromyography (EMG) is an expression of the physiological or pathophysiological state of muscles. Selection of the type of electrode used during these measurements is based upon several factors, including the location of the muscle of interest, the need for specificity, and the requirement of minimization of cross-talk between adjacent muscles. Pneumothorax is a serious complication of needle EMG. Here, we present a 19-year-old patient who suffered bilateral pneumothoraces as a complication of needle EMG. She has a history of weakness and limitation of abduction on her right shoulder for three years. EMG was ordered by orthopedic surgeon to determine whether a dorsal scapular or long thoracic nerve paralysis caused these symptoms. She was brought to our emergency department (ED) with the complaints of diaphoresis and dyspnea which began after needle EMG was performed two hours ago. A chest X-ray revealed bilateral small pneumothoraces and was confirmed by computed thoracic tomography scan. Patient was admitted to observation unit in ED. Thoracic ultrasonography was preferred to follow up the patient. After five days, pneumothoraces were dissolved on bilaterally and the patient was discharged to home. Iatrogenic pneumothorax is a complication observed at various clinical fields. Emergency physician must consider this possibility in patients admitted with dyspnea after needle EMG.
