Suspension of Mechanical Ventilation in Ureteroscopic Lithotripsy Under General Anesthesia

2014-08-27 04:00:41 | BioPortfolio

Summary

For some upper ureteral and renal stones,ureteroscopic lithotripsy needs to be performed under general anesthesia with interrupted suspension of mechanical ventilation, which could result in hypercapnia and hypoxia. In this study, the investigators hypothesize that 10 cmH2O PEEP added to the respiratory circuit with 1 L/min 100% oxygen might extend the time of ventilation suspension but have no effect on carbon dioxide retention in blood.

Description

For some upper ureteral and renal stones,ureteroscopic lithotripsy is often perdurbed by the patient's respiratory movement either under epidural anesthesia or general anesthesia with mechanical ventilation. So intermittent suspension of mechanical ventilation under general anesthesia can ensure the surgery to be performed continuously and successfully. But this could result in hypercapnia and hypoxia. So far, there have been few studies focused on the change of the internal environment in blood as result of suspending breath. In this study, the investigators hypothesize that 10 cmH2O PEEP added to the respiratory circuit with 1 L/min 100% oxygen might extend the time of ventilation suspension but have no effect on carbon dioxide retention in blood.

Clinical Trials [110 Associated Clinical Trials listed on BioPortfolio]

Assessment of Cerebral Vasoreactivity Using Near-infrared Spectroscopy (NIRS) in Infants (VARO)

The purpose of this study is to show that a permissive hypercapnia during mechanical ventilation in children under general anaesthesia will improve cerebral perfusion.

Effects of Positive End-expiratory Pressure on Intracranial Pressure in Patients With Severe Traumatic Brain Injury

The impact of PEEP on ICP was dependent on the difference between elevated CVP levels and baseline ICP levels. ICP would increase once elevated CVP through PEEP adjustment exceeds the base...

Hypercapnia During Shoulder Arthroscopy

The purpose of this study is to evaluate the effects of hypercapnia on hemodynamics and cerebral oxygenation during shoulder arthroscopy.

Effect of Positive End Expiratory Pressure at the Time of Induction in Morbidly Obese Patients

Background: Positive end expiratory pressure (PEEP) at the time of induction increases oxygenation by preventing lung atelectasis. However, PEEP may not prove beneficial in all cases. Fact...

Open Lung Strategy, Gas Distribution and Right Heart Function in ARDS Patients

The goal of this interventional crossover study, in intubated and mechanically ventilated Acute Respiratory Distress Syndrome (ARDS) patients, is to compare two positive end-expiratory pre...

Delivery of positive end-expiratory pressure to preterm lambs using common resuscitation devices.

In neonatal resuscitation, a ventilation device providing positive end-expiratory pressure (PEEP) is recommended. There is limited information about PEEP delivery in vivo, using different models of se...

PEEP Lower Than the ARDS Network Protocol is Associated with Higher Pediatric ARDS Mortality.

The ARDS Network used a Positive End-Expiratory Pressure (PEEP)/FiO2 model in many studies. In general, pediatric intensivists use less PEEP and higher FiO2 than this model.

Mechanical ventilation strategies alter cardiovascular biomarkers in an infant rat model.

Mechanical ventilation (MV) is routinely used in pediatric general anesthesia and critical care, but may adversely affect the cardiocirculatory system. Biomarkers are increasingly measured to assess c...

Effect of Lung Recruitment and Titrated Positive End-Expiratory Pressure (PEEP) vs Low PEEP on Mortality in Patients With Acute Respiratory Distress Syndrome: A Randomized Clinical Trial.

The effects of recruitment maneuvers and positive end-expiratory pressure (PEEP) titration on clinical outcomes in patients with acute respiratory distress syndrome (ARDS) remain uncertain.

Positive end-expiratory pressure during resuscitation at birth in very-low birth weight infants: A randomized-controlled pilot trial.

There is limited evidence of the effect of positive end-expiratory pressure (PEEP) during resuscitation soon after birth. Premature neonates may experience respiratory distress from surfactant insuffi...

Medical and Biotech [MESH] Definitions

A clinical manifestation of abnormal increase in the amount of carbon dioxide in arterial blood.

HYPOVENTILATION syndrome in very obese persons with excessive ADIPOSE TISSUE around the ABDOMEN and DIAPHRAGM. It is characterized by diminished to absent ventilatory chemoresponsiveness; chronic HYPOXIA; HYPERCAPNIA; POLYCYTHEMIA; and long periods of sleep during day and night (HYPERSOMNOLENCE). It is a condition often related to OBSTRUCTIVE SLEEP APNEA but can occur separately.

Non-therapeutic positive end-expiratory pressure occurring frequently in patients with severe airway obstruction. It can appear with or without the administration of external positive end-expiratory pressure (POSITIVE-PRESSURE RESPIRATION). It presents an important load on the inspiratory muscles which are operating at a mechanical disadvantage due to hyperinflation. Auto-PEEP may cause profound hypotension that should be treated by intravascular volume expansion, increasing the time for expiration, and/or changing from assist mode to intermittent mandatory ventilation mode. (From Harrison's Principles of Internal Medicine, 12th ed, p1127)

A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)
