Update of the European Society of Anaesthesiology and Intensive Care Medicine evidence-based and consensus-based guideline on postoperative delirium in adult patients.

Postoperative delirium (POD) remains a common, dangerous and resource-consuming adverse event but is often preventable. The whole peri-operative team can play a key role in its management. This update to the 2017 ESAIC Guideline on the prevention of POD is evidence-based and consensus-based and considers the literature between 01 April 2015, and 28 February 2022.

Congestive heart failure and comorbidity as determinants of colorectal cancer perioperative outcomes.

There has been an increase in surgical interventions in frailer elderly with concomitant chronic diseases. The purpose of this paper was to evaluate the impact of aging and comorbidities on outcomes in patients who underwent surgery for the treatment of colorectal cancer (CRC) in Veneto Region (Northeastern Italy). This is a retrospective cohort study in patients ≥ 40 years who underwent elective or urgent CRC surgical resection between January 2013 and December 2015.

Perioperative Management of Elderly patients (PriME): recommendations from an Italian intersociety consensus.

Background: Surgical outcomes in geriatric patients may be complicated by factors such as multiple comorbidities, low functional performance, frailty, reduced homeostatic capacity, and cognitive impairment. An integrated multidisciplinary approach to management is, therefore, essential in this population, but at present, the use of such an approach is uncommon. The Perioperative Management of Elderly patients (PriME) project has been established to address this issue.

Gamma Knife Radiosurgery for Short Unilateral Neuralgiform Headache Attacks with Conjunctival Injection and Tearing (SUNCT) Syndrome: Targeting the Trigeminal Nerve and the Sphenopalatine Ganglion. Case Report and Literature Review.

Background: Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a primary headache syndrome with an unclear pathogenesis, and only in very few cases, SUNCT is secondary to known lesions (secondary SUNCT). Several pharmacological as well as interventional and invasive treatments have been used to treat SUNT cases, with no definitive results. We describe a patient with idiopathic SUNCT syndrome, successfully treated with gamma knife radiosurgery and we report a review of the cases of the literature treated with radiosurgery.

Intravenous fluid therapy for hospitalized and critically ill children: rationale, available drugs and possible side effects.

Human beings are constituted mainly of water. In particular, children's total body water might reach 75-80% of their body weight, compared to 60-70% in adults. It is therefore not surprising, that children, especially hospitalized newborns and infants, are markedly prone to water and electrolyte imbalances.

Cardiovascular risk assessment in the senior population undergoing anesthesia for non-cardiac surgery.

Older patients are underrepresented in major cardiovascular trials, and only relatively healthy elderly patients, with few comorbidities or functional impairments, have been enrolled. As a result, current guidelines are unable to provide evidence-based recommendations for anesthesia treatment of patients aged ≥75 years, undergoing non-cardiac surgical procedures. Effective strategies, aimed at reducing the risk of perioperative cardiac complications, should involve cardiac evaluation using mostly medical history.

Emergence times are similar with sevoflurane and total intravenous anesthesia: results of a multicenter RCT of patients scheduled for elective supratentorial craniotomy.

Background: Nearly every anesthetic agent has been used for craniotomy, yet the choice between intravenous or volatile agents has been considered an area of significant debate in neuroanesthesia. We designed a Randomized Clinical Trial to test the hypothesis that inhalation anesthesia (sevoflurane/remifentanil--group S) reduces emergence time by 5 minutes compared with intravenous anesthesia (propofol/remifentanil--group P) in patients undergoing neurosurgery for supratentorial neoplasms.

Methods: Adult ASA I-III elective patients were randomly assigned to group S or P.

Predictive value of the National Institutes of Health Stroke Scale and the Mini-Mental State Examination for neurologic outcome after coronary artery bypass graft surgery.

Objective: We intended to define the role of the National Institutes of Health Stroke Scale and the Mini-Mental State Examination in identifying adverse neurologic outcomes in a large international sample of patients undergoing cardiac surgery.

Methods: We evaluated 4707 patients undergoing cardiac surgery with cardiopulmonary bypass at 72 centers in 17 countries between November 1996 and June 2000. Prespecified overt neurologic outcomes were categorized as type I (clinically diagnosed stroke, transient ischemic attack, encephalopathy, or coma) or type II (deterioration of intellectual function).

Conscious sedation in the critically ill ventilated patient.

Purpose: The aim of sedation is to provide comfort and minimize anxiety. However, adverse effects are noteworthy, and the optimal end point of sedation in intensive care unit patients is still debated. We analyzed if a level 2 on the Ramsay Scale (ie, awake, cooperative, oriented, tranquil patient) is suitable for an invasive therapeutic approach.

Volume and electrolyte management.

Osmolality is the primary determinant of water movement across the intact blood-brain barrier (BBB), and we can predict that reducing serum osmolality would increase cerebral oedema and intracranial pressure. Brain injury affects the integrity of the BBB to varying degrees. With a complete breakdown of the BBB, there will be no osmotic/oncotic gradient, and water accumulates (brain oedema) consequentially to the pathological process.

Giant intracranial aneurysms treated with deep hypothermia and circulatory arrest.

The use of deep hypothermic circulatory arrest (DHCA), using groin cannulation with the chest closed (CCDHCA), has improved the surgical treatment of large and giant cerebral aneurysms. Twelve consecutive ASA I-II patients (10 women and 2 men), with a mean age of 35 years (range 14 to 55 y) underwent DHCA for clipping or trapping of their aneurysm (giant, n=10; large, n=2; 42% posterior circulation), under balanced general anesthesia. Intraoperative standard monitors were completed with jugular oxygen saturation, pulmonary artery, pulmonary artery occlusion, central venous pressures, electroencephalography, evoked potentials, and cerebral (subdural), and core temperature.

Fluids and the neurosurgical patient.

Few human data exist concerning the impact of fluid administration on brain pathophysiology. Those factors that influence water movement into the brain are examined, in order to provide reasonable recommendations for peri-operative fluid management in the patients with brain pathology.

Intracranial effects of endotracheal suctioning in the acute phase of head injury.

In patients with head injury, endotracheal suctioning (ETS) is a potentially dangerous procedure, because it can increase intracranial pressure (ICP). The purpose of this prospective nonrandomized study was to evaluate the impact of ETS on intracranial dynamics in the acute phase of head injury. Seventeen patients with severe head injury (Glasgow Coma Score < or = 8, range 4-8), sedated and mechanically ventilated, were studied during the first week after trauma.

Remifentanil provides hemodynamic stability and faster awakening time in transsphenoidal surgery.

Unlabelled: In this prospective study, we evaluated the effects of remifentanil in ASA I-II patients undergoing transsphenoidal surgery. After the induction of anesthesia, patients were randomly allocated to the Isoflurane (n = 22, 60% nitrous oxide, isoflurane up to 2% end-tidal) or Remifentanil group (n = 21, 60% nitrous oxide, 0.5% end-tidal isoflurane, remifentanil up to 2 microg x kg(-1) x min(-1)).
