Intraoperative effects of an alveolar recruitment manoeuvre in patients undergoing laparoscopic colon surgery.

Introduction: Pulmonary atelectasis is common in patients undergoing laparoscopic abdominal surgery under general anaesthesia, which increases the risk of perioperative respiratory complications. Alveolar recruitment manoeuvres (ARM) are used to open up the lung parenchyma with atelectasis, although the duration of their benefit has not been clearly established. The aim of this study was to determine the effectiveness of an ARM in laparoscopic colon surgery, the duration of response over time, and its haemodynamic impact.

Late bilateral vocal cord palsy following endotracheal intubation due to COVID-19 pneumonia.

Vocal cord paralysis is a rare but severe complication after orotracheal intubation. The most common cause is traumatic, due to compression of the recurrent laryngeal nerve between the orotracheal tube cuff and the thyroid cartilage. Other possible causes are direct damage to the vocal cords during intubation, dislocation of the arytenoid cartilages, or infections, especially viral infections.

Development and validation of a delirium risk prediction preoperative model for cardiac surgery patients (DELIPRECAS): An observational multicentre study.

Study Objective: To develop and validate a delirium risk prediction preoperative model for patients undergoing cardiac surgery.

Design: Observational prospective multicentre study.

Setting: Six intensive care units in Spain.

[Acute myocardial infarction in the postoperative period following pneumonectomy].

A 72-year-old man, smoker, with insuline-dependent diabetes and dislipemia underwent left pneumonectomy. Several episodes of intraoperative hemodynamic instability associated with electrocardiographic ST segment alterations were attributed to surgical manipulation; ischemia was not suspected. Cardiorespiratory failure, related to extensive anterior infarction, developed a few minutes after admission to the postoperative intensive care unit (PICU).

[The effect of propofol vs desflurane on recovery from anesthesia with remifentanil in outpatient surgery].

Objectives: To compare the effect on parameters of postanesthetic recovery of propofol and desflurane administered with high doses of remifentanil for major outpatient surgery.

Patients And Methods: Seventy patients were randomly assigned to receive propofol (target concentration 1.5-2 microg/ml) or desflurane in perfusion (end expiratory concentration 0.

[Malignant hyperthermia in a pig anesthesized with desflurane].

A large-white pig that had not been genetically selected to develop malignant hyperthermia (MH) during anesthesia nevertheless suffered an episode of severe MH after repeated exposure to increasing concentrations of desflurane. MH is a hypermetabolic alteration that may develop in susceptible patients who have inhaled certain drugs or agents that act as triggers. Early identification and appropriate treatment are essential to reduce the likelihood of death associated with this severe alteration.

Low-flow anesthesia and reduced animal size increase carboxyhemoglobin levels in swine during desflurane and isoflurane breakdown in dried soda lime.

Unlabelled: After institutional approval, we studied the effect of animal size, anesthetic concentration, and fresh gas flow (FGF) rate on inspired carbon monoxide (CO) and carboxyhemoglobin (COHb) during anesthesia in swine, using soda lime previously dried to 1 +/- 0.1% water content. To ascertain the effect of anesthesia, eight adult pigs were anesthetized with either 1 minimum alveolar anesthetic concentration (MAC) desflurane or isoflurane and, to characterize the effect of the FGF rate, it was doubled in four pigs.

[Epidural abscess secondary to the implantation of a thoracic catheter].

Spinal compression related to the formation of an epidural abscess after epidural blockade is a rare but serious complication. We report the case of a male patient in whom a thoracic epidural catheter was implanted to provide analgesia after trauma involving fracture ribs. The patient developed an epidural abscess within one week of implantation.

[Quantification of dehydration of soda lime in clinical circumstances].

Hypothesis And Objectives: When the CO2 absorbents, soda lime and baralime, have lost their normal level of hydration, they may react with certain halogenated anesthetics to produce appreciable levels of carbon monoxide. The degree of absorbent desiccation has been considered the limiting factor for this phenomenon. This study quantifies the level of dehydration of lime produced under clinical conditions and the influence of several factors.

[Late paraparesis as a postoperative complication in a patient undergoing the repair of a double aortic aneurysm].

We report a case of a fifty-seven (57)-years old man undergoing elective surgery of a thoracoabdominal and aortoiliac aneurysm in a single surgical time. The patients is operated undergoing general anesthetic combined with thoracic epidural blockade, and it was done two aortic cross-clamping: one to five cm of the aortic arch and the other to the infrarenal level. The most important intraoperative complications were during the thoracic aortic cross-clamping and the most important postoperative complication was related 48 hours later, to paraparesis after a hypotension episode what improved with rehabilitation treatment.
