Effect of varying cuff sizes with identical inner diameter on endotracheal intubation in critically ill adults: A sealed tracheal controlled trial.

Background: The present study aims to determine the impact of different cuff diameters on the cuff pressure of endotracheal tubes (ETTs) when the trachea is adequately sealed.

Methods: In the present single-center clinical trial, adult patients who underwent cardiothoracic surgery were assigned to use ETTs from 2 brands (GME and GZW). The primary endpoint comprised of the following: cuff diameter, inner diameter of the ETT, manufacturer, and the number of subjects with tracheal leakage when the cuff pressure was 30 cm H2O.

Factors associated with lack of tracheal sealing by a cuff inflated to more than 30 cmHO during mechanical ventilation: A cross-sectional study.

Objectives: The cuff pressures > 30 cmHO may create a seal in the trachea. The objective of this study was to identify risk factors associated with lack of tracheal sealing by an endotracheal cuff inflated to > 30 cmHO in patients undergoing mechanical ventilation.

Methods: This prospective cross-sectional study was conducted from 2019 to 2020 in the cardiothoracic intensive care unit and respiratory medical care unit of a Hospital in Nantong, China.

Endotracheal cuff undersizing diagnosed by computed tomography: Case report.

We herein report a case in which the trachea could be completely sealed only when the cuff pressure reached 100 cmHO. An excessive cross-sectional area of the trachea is a rare phenomenon, but we believe that our case will be helpful for clinicians who encounter similar situations.

A Method by Disposable Medical Hydrogel to Reduce Water Vapor in Goggles.

In this letter, we describe a method about disposable medical hydrogel recommended inside surgical masks to reduce the water vapor in the goggles. The introduction is as follows.Level of Evidence V This journal requires that authors assign a level of evidence to each article.

The Physical Vapor Transport Method for Bulk AlN Crystal Growth.

In this report, the development of physical vapor transport (PVT) methods for bulk aluminum nitride (AlN) crystal growth is reviewed. Three modified PVT methods with different features including selected growth at a conical zone, freestanding growth on a perforated sheet, and nucleation control with an inverse temperature gradient are discussed and compared in terms of the size and quality of the bulk AlN crystals they can produce as well as the process complexity. The PVT method with an inverse temperature gradient is able to significantly reduce the nucleation rate and realize the dominant growth of only one bulk AlN single crystal, and thus grow centimeter-sized bulk AlN single crystals.

Simultaneous endoscopic submucosal dissection for multiple early gastric cancers in a low volume center.

The aim of the study is to evaluate the safety and efficacy of simultaneous endoscopic submucosal dissection (ESD) for multiple early gastric cancers.A total of 70 solitary early gastric cancers from 70 patients and 20 multiple early gastric cancers from 10 patients were included in this retrospective study. The curative resection rate, en bloc resection rate, procedure-related complications, and local recurrence were compared between the 2 groups.

5% NaHCO Is Appropriate for Skin Cleaning With Central Venous Catheters.

Objectives: The purpose of this study was to compare the effects of skin cleaning with 5% NaHCO to 75% alcohol on the removal of skin grease and pain of patients with central venous catheters (CVC).

Materials And Methods: This was a randomized, controlled, single-blinded and prospective study. From January-September 2015, 143 consecutive patients who met the inclusion and exclusion criteria and who underwent elective cardiovascular surgery with placement of a CVC were selected.

Relationship of tidal volume to peak flow, breath rate, I: E and plateau time: mock study.

Background: The purpose of this study was to determine the functional relationship between tidal volume (VT) and 4 other ventilator parameters.

Methods: The following parameters were collected from an AVEA ventilator operating in the volume-controlled ventilation mode: VT (in L), peak flow (Vmax, in L/min), breath rate (f, in bpm), inspiratory-to-expiratory time ratio (I:E) and plateau time (TP, in s). The relationship between VT and each of the other variables was determined.

Superiority of 5% NaHCO3 for preoperative hair removal in patients undergoing coronary artery bypass graft surgery with a limb vein: a randomized controlled trial†.

Objectives: Compared with a dry environment with talcum powder, a wet, alkaline environment with NaHCO3 solution is better for hair removal, as it can soften and expand the hair, decrease the friction and shear forces on the skin, and make hair removal easier and more efficient. The purpose of this study was to compare the effects of a preoperative skin preparation of 5% NaHCO3 with that of talcum powder for softening hair in patients undergoing coronary artery bypass graft (CABG) surgery with the saphenous vein.

Methods: A prospective randomized, single-blinded, controlled study was established.

Evaluation of Nrf2 and IGF-1 expression in benign, premalignant and malignant gastric lesions.

The aim of this study was to investigate the expression of Nrf2 and IGF-1 in benign, premalignant, and malignant gastric lesions, and to explore the role of Nrf2 and IGF-1 in gastric carcinoma carcinogenesis. Nrf2 and IGF-1 expression was detected in normal gastric mucosa, hyperplastic polyp, intraepithelial neoplasia, and adenocarcinoma by immunohistochemistry. There was no expression of Nrf2 and IGF-1 in normal gastric mucous membrane.

[The association of TGF beta1 and AT1R gene polymorphisms with hereditary susceptibility and clinical phenotype of HBV-induced liver cirrhosis].

Objective: To investigate the association of TGF beta1 and AT1R gene polymorphisms with hereditary susceptibility and clinical phenotype of HBV-induced liver cirrhosis.

Methods: Peripheral blood samples were collected from 102 patients with HBV-induced liver cirrhosis and 106 healthy blood donors. The polymorphisms of the promoter site -509C/T of TGF beta1 and 1166A/C of AT1R gene were determined by PCR-RFLP.
