“…[14][15][16][17]19] According to Simpson et al, [14] capnography should be used to confirm ETT position in all intubations, including those performed outside the operating theatre. [13] Delorio [15] confirmed that capnography is the recommended method for ETT verification, but also recognised that the use of capnography is limited and is often either not available or inconsistently applied in ETT verification. Dittrich [16] confirmed that capnography is the most reliable method for verification of the ETT.…”

“…However, when all three bedside methods were combined, sensitivity was higher than observing the centimetre scale alone. Varshney et al [13] reported in their study that the centimetre scale printed on the ETT could be used as a verification method. They suggested that optimal depth of the ETT placement could be estimated by means of a formula: height in cm/7 -2.5.…”

“…Ballottement was also found to lead to complications due to pain and unwanted rise in both blood and intracranial pressures, and is therefore not recommended for use in the critical care setting. [13,18] This method is thus not recommended for ETT placement verification. [12] 160 adult ICU patients who underwent elective surgery…”

Objective. To explore the methods that can be used to verify endotracheal tube (ETT) placement in adult mechanically ventilated patients.Methods. An integrative literature search was conducted in 2012 -2013 of research citations published in English on the topic of discussion. Electronic databases searched were: the Cumulative Index of Nursing and Allied Health (CINAHL), MEDLINE, PubMed, the Joanna Briggs Institute (JBI) systematic review library, the Cochrane Library and the National Guidelines Clearinghouse. In addition, reference lists of articles, conference summaries and hand searching was performed. Citations were selected based on the inclusion and exclusion criteria as decided upon by the researchers. The process of critical appraisal was done by the researchers as well as an independent reviewer, all skilled in the research methodology and subject matter related to the topic of discussion. A total of 45 articles were included for critical appraisal. On completion of the critical appraisal, which was done by two independent reviewers, 34 articles were excluded and 11 articles were included in the integrative review analyses. Data were extracted following the critical appraisal process. Owing to the heterogeneity of studies, a metasynthesis could not be done. Results. Based on the reviewed studies, various methods have been identified to verify ETT placement in adult mechanically ventilated patients, namely ultrasonography, the use of centimetre scale printed on the ETT, manual cuff palpation, bilateral auscultation of chest and palpation of symmetrical chest movements, oesophageal detector devices, visualisation of the ETT, use of chest X-ray, pulse oximetry and capnography. Both ultrasonography and capnography had excellent sensitivity and specificity in verifying ETT placement. Conclusion. Although there are various methods reported for ETT verification, the review results recommended ultrasonography and capnography as the most accurate and reliable verification methods.

Organic-inorganic nanocomposites poly-o-anisidine and poly-o-toluidine Sn(IV) tungstate were chemically synthesized by mixing organic polymers that is, o-anisidine and o-toluidine with inorganic gels of Sn(IV) tungstate in different mixing ratios. Ion-exchange kinetics for few divalent metal ions was evaluated by particle diffusion-controlled ion-exchange phenomenon at four different temperatures. The particle diffusion mechanism was confirmed by linear τ (dimensionless time parameter) versus t (time) plots. The exchange processes were controlled by the diffusion of ions within the exchanger particle for the systems under studies. Some physical parameters such as self-diffusion coefficient (D • ), energy of activation (E a ), and entropy of activation ( S • ) were evaluated under conditions favoring a particle diffusion-controlled mechanism.

Purpose To evaluate risk factors associated with improper postoperative nasal Ring-Adair-Elwyn (RAE) tube depth. Methods We retrospectively enrolled 133 adult patients who were admitted to the intensive care unit (ICU) with the nasal RAE tube after head and neck surgery. Postoperative chest radiography was performed to confirm nasal RAE tube depth immediately after the patient was admitted to the ICU. Proper tube depth was defined as the tube tip between 2 and 7 cm above the carina. The patients were divided into the proper-depth group (78 patients) and the improper-depth group (55 patients). Patients' characteristics were collected. The risk factors for improper postoperative tube depth were assessed using logistic regression analysis. Main results All patients who showed improper tube depth had a shallow tube depth (the tube tip > 7 cm above the carina). Multivariable analysis revealed that tall stature [odds ratio (OR) 1.16; 95% confidence interval (CI) 1.08-1.25; P < 0.001], prolonged anesthesia duration (OR 1.16; 95% CI 1.02-1.32; P = 0.026), and right-sided surgical field as compared to the left (OR 0.36; 95% CI 0.14-0.93; P = 0.034) or median field (OR 0.25; 95% CI 0.07-0.85; P = 0.027) were risk factors associated with postoperative shallow tube depth. Conclusions Tall stature, prolonged anesthesia duration, and right-sided surgical field were independent risk factors for postoperative shallow nasal RAE tube depth.
