BACKGROUND In patients breathing spontaneously during anaesthesia, expiration is active and opioids enhance this effect. The mechanical consequences are not well characterized. METHODS We studied 14 patients undergoing laparoscopy for minor gynaecological procedures, anaesthetized with isoflurane in nitrous oxide, and breathing spontaneously through a laryngeal mask airway. We made direct rec...

In cases of acute severe pancreatitis mortality rate remains high. Few of these patients develop increased intra abdominal pressure. This study used utility of intra abdominal pressure monitoring to assess severity of severe acute pancreatitis and its comparison with CT severity index and to predict prognosis of patients of acute severe pancreatitis by measuring intra abdominal pressure and to ...

[Purpose] The leg angles that are the most effective for abdominal muscle activation were investigated by performing abdominal drawing-in exercises at different leg angles with a biofeedback pressure unit. [Methods] Subjects were asked to adopt a supine position, and the tip of the biofeedback pressure unit was placed under the posterior superior iliac spine. Then, the pressure was adjusted to ...

Objective: To assess the amount of abdominal pressure generated by the Non-pneumatic Anti-Shock Garment (NASG), a first-aid counter pressure device for obstetric hemorrhage, and to evaluate if body mass index (BMI) and applier strength, affect pressure. Study Design: A pilot study convenience sample of 20 non-pregnant volunteers underwent external abdominal pressure monitoring with NASG placeme...

Superior vena cava (SVC) and inferior vena cava (IVC) pressures were measured serially during laparoscopic cholecystectomy in which the intra-abdominal pressure was maintained at 12 mmHg. The influences of alteration of position from 15 degrees head-down to 15 degrees head-up and of the operative procedure of holding the gallbladder up to the right subphrenic space on SVC and IVC pressures were...

Thoraco-abdominal asynchrony is frequently encountered during inhalation anaesthesia in children with adenotonsillar hypertrophy causing an upper airway obstruction. The study goal was to evaluate the impact of different airway opening manoeuvres on thoraco-abdominal asynchrony as a measure of airway obstruction. Thirty anaesthetized children (aged 2-8 yrs; sevoflurane 3% in 50% oxygen/nitrous ...

Intra-abdominal hypertension falsely elevates the pulmonary artery pressure. Volumetric pulmonary artery catheter monitoring is an optionfor estimating preload in this condition. Treatment of intra-abdominal hypertension begins with medical therapy but once abdominal compartment syndrome develops it requires decompressive laparotomy for definitive management. Pulmonary hypertension reduces card...

In the future, medical management may play an increasingly important role in the prevention and management of intra-abdominal hypertension (IAH). A review of different databases was used (PubMed, MEDLINE and EMBASE) with the search terms 'Intra-abdominal Pressure' (IAP), 'IAH', ' Abdominal Compartment Syndrome' (ACS), 'medical management' and 'non-surgical management'. We also reviewed all pape...

There is a growing request for measuring intra-abdominal pressure in critically ill patients with acute abdominal pain to be clarified. Summarizing the research results on measurement of vesical intra-abdominal pressure and analyzing the level of evidence were the purposes of this integrative literature review, carried out based on the databases LILACS, MEDLINE and PubMed, from 2005 to July 201...

BACKGROUND Hospital mortality in patients with severe acute pancreatitis (SAP) remains high. Some of these patients develop increased intra-abdominal pressure (IAP) which may contribute to organ dysfunction. The aims of this study were to evaluate the frequency of increased IAP in patients with SAP and to assess the development of organ dysfunction and factors associated with high IAP. METHOD...
