BACKGROUND Ventilation through small-diameter tubes typically precludes use of a cuff as this will impede the necessary passive outflow of gas alongside the tube's outer surface. Ventrain assists expiration and enables oxygenation and normoventilation through small-bore cannulas or catheters, particularly in obstructed airways. A small-bore ventilation catheter (SBVC; 40 cm long, 2.2 mm inner d...

BACKGROUND Untrained fingertip palpation has been shown to be unable to adjust endotracheal tube (ET) cuff pressure in most intubated patients. OBJECTIVE We determined the impact of a training course of ETT cuff adjustment by palpation in attaining a safe cuff inflation pressure. PATIENTS AND METHODS Twenty-five nurses were asked to adjust the ETT cuff pressure to 25 cmH2O by palpation on t...

The objective of this study was to investigate the national trends in rotator cuff surgery in Korea and analyze hospital type-specific trends. We analyzed a nationwide database acquired from the Korean Health Insurance Review and Assessment Service (HIRA) from 2007 to 2015. International Classification of Diseases, 10th revision (ICD-10) codes, procedure codes, and arthroscopic device code were...

1310 Communications to the Editor cuff inflation is seldom seen, and an increase of 1 ml or less in cuff volume can markedly increase LW? What can be done to minimize the possibility of cuff-induced tracheal damage? First, select the largest endotracheal tube that can be inserted atraumatically. A greater cross-sectional area ratio between the tube and the trachea means less air must be injecte...

BACKGROUND AND PURPOSE We describe the structural abnormalities in the painful shoulder of stroke survivors and their relationships to clinical characteristics. Method- Eighty-nine chronic stroke survivors with poststroke shoulder pain underwent T1- and T2-weighted multiplanar, multisequence MRI of the painful paretic shoulder. All scans were reviewed by one radiologist for the following abnorm...

When revising failed double-row and suture-bridge rotator cuff repairs medial failures represent a potential feature. In the presence of a compromised healing environment, patch augmentation becomes a logical adjunct from a mechanical and biological point of view. A reproducible step-by-step revision technique is described that reinforces the weak central cuff area with an absorbable synthetic ...

Ideally, interference in neural measurements due to signals from nearby muscles can be completely eliminated with the use of tripolar nerve cuff electrodes, in combination with appropriate amplifier schemes. In practice the cuff departs from its ideal model leading to cuff imbalance. As a result, the output nerve signal of such amplifiers has been widely reported to be degraded by interference,...

The long head of biceps tendon (LHBT) is frequently involved in rotator cuff tears and can cause anterior shoulder pain. Tendon hypertrophy, hourglass contracture, delamination, tears, and tendon instability in the bicipital groove are common macroscopic pathologic findings affecting the LHBT in the presence of rotator cuff tears. Failure to address LHBT disorders in the setting of rotator cuff...

Nitrous oxide (N2O) is an inhalational anesthetic that is frequently used for general anesthesia. While N2O is not sufficient for maintaining general anesthesia if used alone, when used in combination with a volatile inhalation agent, N2O decreases the minimum alveolar concentration (MAC) of the volatile inhalational agent, thereby reducing the amount of the agent required during longer procedu...
