Background and Objectives:Over the past few years, ultrasonography is increasingly being used to confirm the correct placement of endotracheal tube (ETT). In our study, we aimed to compare it with the traditional clinical methods and the gold standard quantitative waveform capnography. Two primary outcomes were measured in our study. First was the sensitivity and specificity of ultrasonography against the other two methods to confirm endotracheal intubation. The second primary outcome assessed was the time taken for each method to confirm tube placement in an emergency setting.Methods:This is a single-centered, prospective cohort study conducted in an emergency department of a tertiary care hospital. We included 100 patients with indication of emergency intubation by convenient sampling. The intubation was performed as per standard hospital protocol. As part of the study protocol, ultrasonography was used to identify ETT placement simultaneously with the intubation procedure along with quantitative waveform capnography (end-tidal carbon dioxide) and clinical methods. Confirmation of tube placement and time taken for the same were noted by three separate health-care staffs.Results and Discussion:Out of the 100 intubation attempts, five (5%) had esophageal intubations. The sensitivity and specificity of diagnosis using ultrasonography were 97.89% and 100%, respectively. This was statistically comparable with the other two modalities. The time taken to confirm tube placement with ultrasonography was 8.27 ± 1.54 s compared to waveform capnography and clinical methods which were 18.06 ± 2.58 and 20.72 ± 3.21 s, respectively. The time taken by ultrasonography was significantly less.Conclusions:Ultrasonography confirmed tube placement with comparable sensitivity and specificity to quantitative waveform capnography and clinical methods. But then, it yielded results considerably faster than the other two modalities.
In caustic ingestion injury, the urgent assessment of the airway is the first priority with a definitive airway secured in those with airway compromise. In those patients with a stable airway and no clinical or radiological sign of perforation, then medical therapy should be commenced and an urgent oesophagogastroduodenoscopy (OGD) is arranged and this should take place within the first 24 h to grade the degree of injury and establish long-term prognosis. In suspected perforation, a surgical opinion should be sought. For those adults who are asymptomatic following ingestion an OGD may not be necessary; however, asymptomatic paediatric patients should be treated with more caution and a period of observation is important. Those who are at risk of developing late complications must be followed up.
Ultrasound-guided peripheral nerve blocks facilitate ambulatory anesthesia for upper limb surgeries. Unilateral phrenic nerve blockade is a common complication after interscalene brachial plexus block, rather than the supraclavicular block. We report a case of severe respiratory distress and bilateral bronchospasm following ultrasound-guided supraclavicular brachial plexus block. Patient did not have clinical features of pneumothorax or drug allergy and was managed with oxygen therapy and salbutamol nebulization. Chest X-ray revealed elevated right hemidiaphragm confirming unilateral phrenic nerve paresis.
PurposeTo describe data on epidemiology, microbiology, clinical characteristics and outcome of adult ICU patients with secondary peritonitis, with special emphasis on antimicrobial therapy and source control. Methods Post hoc analysis of a multicenter observational study (Abdominal Sepsis Study, AbSeS ) including 2621 adult ICU patients with intra-abdominal infection in 306 ICUs from 42 countries. Time-till-source control intervention was calculated as from time of diagnosis and classified into 'emergency' (<2 hours), 'urgent' (2-6 hours), and 'delayed' (>6 hours). Relationships were assessed by logistic regression analysis and reported as odds ratios (OR) and [95% confidence interval].
ResultsThe cohort included 1077 cases of microbiologically confirmed secondary peritonitis. Mortality was 29.7%. The rate of appropriate empiric therapy showed no difference between survivors and non-survivors (66.4% vs . 61.3%, p=0.102). A stepwise increase in mortality was observed with increasing SOFA scores (19.6% for a value £4 to 55.4% for a value >12, p<0.001). The highest odds of death were associated with septic shock .00]), late-onset hospital-acquired peritonitis ) and failed source control evidenced by persistent inflammation at Day 7 ). Compared with 'emergency' source control intervention (<2 hours of diagnosis), 'urgent' source control was the only modifiable covariate associated with lower odds of mortality ). Conclusions 'Urgent' and successful source control were associated with improved odds of survival. Appropriateness of empirical antimicrobial treatment did not significantly affect survival suggesting that source control is more determinative for outcome.
The RHINO-ooze scoring tool demonstrates good specificity and sensitivity in predicting the risk of 30 day readmission in patients with epistaxis and can be used as an adjunct to clinical decision making with regards to timing of operative intervention in order to reduce readmission rates.
