Does Deflating the Tracheal Cuff Shorten Weaning Time?

The purpose of this study is to determine whether deflating the tracheal cuff in tracheostomized patients, during disconnections from ventilatory support along the weaning phase shortens the weaning time.

Assessment of Cough Strength in Patients With Tracheostomies

We propose to assess cough strength in patients undergoing spontaneous breathing trials in the IICU and compare their cough strength under two conditions, 1. Tracheostomy cuff inflated: cough strength will be measured with the tracheostomy cuff inflated and the patient coughing through the tracheostomy tube. 2. Tracheostomy cuff deflated: cough strength will be measured with the tracheostomy cuff deflated and the patient coughing around the tracheostomy tube, th...

Continuous Control of Tracheal Cuff Pressure and Microaspiration in Critically Ill Patients

We hypothesized that continuous control of tracheal cuff pressure would reduce microaspiration of gastric content as determined by pepsin level in tracheal aspirate.

The Effect of Esophageal Temperature Probe Insertion on Tracheal Cuff Pressure

The goal of this prospective observational study is to investigate the effect on esophageal stethoscope insertion on tracheal cuff pressure during general anesthesia.


The Ornge Comparison of Tracheal Occlusion Pressures to Ensure Safety Trial

Patients who are intubated (breathing tube in windpipe) are often transported by air ambulance. Changes in atmospheric pressure during flight may cause pressure increases in the air-filled cuff holding the tube in the windpipe. Studies show that more than half the patients had potentially harmful pressures in the cuff during flight. High pressures lead to complications, such as injury to the windpipe. To avoid injury, cuff pressures must be kept at a safe level. There are ...

The Status of Autonomic Tone Before Tourniquet Deflation During Total Knee Replacement

This study evaluates the influences of the status of sympathovagal balance before tourniquet deflation on a decrease in arterial blood pressure following the deflation during total knee replacement arthroplasty

Comparison of Two Protocols for Deflation of Radial Band Following Coronary Procedures Via the Radial Artery

Coronary angiography is now mainly performed via the radial route rather than the femoral route. At the end of the procedure, the sheath is removed and a band is inflated to obtain hemostasis. The air in the band is then deflated at regular intervals. Currently there are different protocols for deflation of the band, but none of these have been studied with regards to patient comfort and time of deflation, and potential complications such as bleeding. Here in this study the inv...

Remote Ischaemic Preconditioning Combined With Exercise Training on Vascular Function.

Remote Ischaemic preconditioning' (RIPC) is defined as short controlled sequences of repeated inflation of a blood pressure cuff on the upper arm (to reduce blood flow) for 5 mins followed by recovery (cuff deflation so blood flows normally again). An intervention consisting of 4 cycles of 5 min of arm cuff inflation followed by deflation performed 3 times per week, spread over 8 weeks has been shown to improve blood vessel function in young individuals without any medical cond...

Cuff Pressure in Infants

The changes in the cuff pressure in the absence of nitrous oxide are less clear.In the current study, we aim to determine the changes in cuff pressure over time in infants undergoing myelomeningocele repair in prone position under general anesthesia in the absence of N2O.

Effects of Tracheal Tube Size on Pulmonary Aspiration

Fluid leak around the cuff is minimized when the endotracheal tube size is small relative to the size of the trachea. In the current study, the investigators assess the influence of different HVLP endotracheal tube size on fluid leakage around the cuff in a benchtop model and in anesthetized patients.

Minimal Occlusive Pressure With Cuffed ETTs: A Comparison of Two Different Techniques to Ensure a Tracheal Seal

In the past 5 years cuffed endotracheal tubes (ETT) have become the standard of care in pediatrics. However, hyperinflation of the cuff can compromise the tracheal mucosal perfusion while an inadequate seal may impact ventilation and potentially increase the risk of aspiration. Hence, the goal after placement of a cuffed ETT is to create a safe and effective tracheal seal. The two ways to measure that are to hold CPAP while listening for an audible leak and measuring the differ...

B-type Natriuretic Peptide for the Management of Weaning

Several clinical findings and clinical trials have suggested that the prognosis of intensive care unit (ICU) patients may be improved by minimizing the positive fluid balance. In particular, a global vascular overload could lead to weaning failure. The purpose of this international, multicenter, controlled, randomized trial is to test if the incorporation of a B-type natriuretic peptide (BNP) assay in a mechanical ventilation weaning protocol helps optimize the weaning process ...

Oximetry Guided Versus Traditional Rapid Deflation Technique for Achieving Hemostasis After Radial Procedures

After performing a radial angiography/percutaneous coronary intervention (CAG/PCI), the sheath is removed and a compression device is used to achieve hemostasis. Recent studies have indicated that rapid deflation techniques resulting in early removal of the compression device is associated with a low incidence of radial artery occlusion (RAO). The purpose of the present study is to evaluate whether an even faster removal of the compression device can be achieved if using oxime...

Analysis of Local and Circulating Compounds Released Following Blood Pressure Cuff Inflation

This study aims to analyze the way the human body responds to a temporary lack of oxygen, or ischaemia. Prospective participants will complete a health screen to confirm overall health / low cardiovascular risk profile.The participants will be required to have pneumatic blood pressure cuff inflation to 200mmHg on the upper arm for 5 minutes which will then be deflated for 5 minutes and then repeating the cycle of inflation and deflation a further 3 times. Blood tests from veins...

Prevention Inhalation of Bacterial by Using Endotracheal Tube Balloon Polyvinyl Chloride or Polyurethane

A number of techniques have been recommended for the prevention of ventilator acquired pneumonia (VAP). These techniques - such as patient positioning, continuous sub-glottic suction of the secretions, selective decontamination of the digestive tract etc… - aim at prevent the inhalation of oro-pharyngeal contaminated secretions around the cuff of the tracheal tube used for connecting the patient to the machine. Their efficacy has been regularly challenged and they are still u...

Intravenous Lidocaine to Supress of Cough Reflex During Anesthesia Emergence

Introduction: Although inflating tracheal cuff using lidocaine is effective for cough suppression, it may pressure tracheal cuff too much. Intravenous continuous infusion of lidocaine has emerged recently for most general anesthesia in the context of opioid-sparing anesthesia for cancer, but the 95% effective dose (ED95) for cough suppression during anesthesia emergence is not determined yet. Objective: the objectives of this study are to determine the ED95 of continuous infusi...

Role of Diaphragm Fatigue in Weaning From Mechanical Ventilation

The purpose of this study is to determine whether the diaphragm develops contractile fatigue during a weaning trial and if this is associated with weaning failure.

Tracheal Palpation of Sliding Cuff to Assess Endotracheal Tube Location

Correct endotracheal tube (ETT) placement is important. Proper ETT position is achieved when the distal tip is in mid-trachea with the head in neutral alignment. Unrecognized tube misplacement is an uncommon but significant cause of hypoxemia and death during general anesthesia as well as in the care of critically ill patients. Hypotheses: A specific manoeuvre to palpate the inflated ETT cuff, with fingers anterior to the trachea, moving the ETT caudally then rostrally followi...

Does Tracheal Suction During Extubation in Intensive Care Unit Decrease Functional Residual Capacity

Little is known about the procedure of extubation of patients admitted in Intensive Care Units (ICU). In particular, effects of tracheal suction during extubation have never been evaluated. Tracheal suction induces alveolar derecruitment in sedated patients under mechanical ventilation and is a major source of pain. The aim of this study was to evaluate the impact of tracheal suction during the extubation procedure of critically ill patients on the end-expiratory lung volume.

Postoperative Analgesic Requirements for the ProSeal Laryngeal Mask Airway Versus the Tracheal Tube in Females Undergoing Gynecological Laparoscopic Surgery

The ProSeal laryngeal mask airway is a relatively new airway device with a modified cuff to increase the seal and a drain tube to provide a channel for regurgitated fluid, prevention of gastric insufflation and insertion of a gastric tube. In the following randomized prospective double-blind trial, we test the hypothesis that the postoperative analgesic requirements is higher for the ProSeal laryngeal mask airway than the tracheal tube.

Voices of Patients' Relatives to Support Weaning From Mechanical Ventilation

Patients with severe brain injuries, such as ischemic stroke and intracranial hemorrhage, frequently require mechanical ventilation. Weaning of stroke patients is complicated by impaired consciousness and respiratory drive. Higher rates of weaning failure and delayed extubation (≥ 48h) lead to ventilator associated pneumonia, higher mortality and necessity of tracheostomy. Therefore, improving the weaning of stroke patients from mechanical ventilation is warranted to p...

I-gel Versus C-LMA as a Conduit for Tracheal Intubation Using Ventilating Bougie

Supraglottic Airway devices(SGAs) like I-Gel and C-LMA ( classic laryngeal mask airway ) have been used as a conduit for tracheal intubation using ventilating bougie. General Anaesthesia with tracheal intubation is one of the technique for giving anaesthesia. Tracheal intubation may become difficult sometimes and endangers patients life. Using SGAs as a conduit for tracheal intubation helps in securing airway. This will be further facilitated by using ventilating bougie, as it ...

Endothelial Dysfunction in Perioperative Period

Study will enroll patients scheduled for hip arthroplasty. In each subject a flow-mediated dilatation capability (FMD) of the brachial artery will be measured prior to elective surgery, within 24 hours after surgery and 5-7 days after surgery. At each session the brachial artery diameter will be measured at rest, during cuff inflation and 50 seconds after cuff deflation. From above mentioned values the increase in the diameter of the artery during reactive hyperemia will be cal...

Effect of Increased Muscular Work During Different Weaning Strategies in Critically Ill Patients

Most patients admitted to intensive care units require mechanical ventilation. Weaning from assisted/controlled ventilation begins when we recognize that the patient has recovered adeguately from acute respiratory failure. If weaning is delayed, costs are increased, as are the risks of nosocomial pneumonia, cardiac-associated morbility, and death. On the other hand, weaning too soon often results in reintubation, which is associated with complications similar to those of prolo...
