Multicenter Study Observational Study
Tissue oxygen saturation changes and postoperative complications in cardiac surgery: a prospective observational study.
Cardiac surgery with extracorporeal circulation (ECC) can induce microvascular dysfunction and tissue hypoperfusion. We hypothesized that the alterations in near-infrared spectroscopy (NIRS)-derived parameters would be associated with post-operative complications in cardiac surgery patients. ⋯ Peripheral tissue oxygen extraction and microvascular reactivity were reduced during the first hours after cardiac surgery. NIRS-derived parameters were not able to predict complications in this population of cardiac surgery patients.

Randomized Controlled Trial Comparative Study
Ice versus lidocaine 5% gel for topical anaesthesia of oral mucosa - a randomized cross-over study.
Topical anaesthesia is important to optimize pain control during dental injection. Our aim was to describe a new simple method for topical anaesthesia of oral mucosa and to compare the effectiveness of ice and lidocaine 5% gel for topical anaesthesia of oral mucosa. ⋯ The cheap and readily available described method using ice for topical anaesthesia of oral mucosa before dental injection is an effective alternative to lidocaine 5% gel.

We aim to describe the evaluation and management of a patient with the uncommon combination of both mitochondrial myopathy and possible malignant hyperthermia susceptibility as an important source of information and as a valuable example of the role of regional anesthesia for patients with these diagnoses. ⋯ Anesthetic management of patients with mitochondrial myopathy is challenging, made even more so with concurrent malignant hyperthermia susceptibility. This case adds an example to the literature of employing regional anesthesia as a safe approach to this complex care.

Randomized Controlled Trial Comparative Study
Comparison of sciatic nerve block quality achieved using the anterior and posterior approaches: a randomised trial.
The co-administration of sciatic and femoral nerve blocks can provide anaesthesia and analgesia in patients undergoing lower extremity surgeries. Several approaches to achieve sciatic nerve block have been described, including anterior and posterior approaches. ⋯ Anterior and posterior approaches can be used to achieve sciatic nerve block in patients undergoing surgery for malleolar fractures. However, better anaesthesia and pain control results can be obtained if analgesia is administered preoperatively in patients with a posterior approach block and after the start of the operation in patients with an anterior approach block.

Tracheostomy is a standard procedure in critically ill patients requiring mechanical ventilation or airway protection for extended periods. The main cause of death is haemorrhage, most commonly owing to a trachea-to-innominate artery fistula, usually requiring surgical treatment. ⋯ The use of peri-procedural ultrasound examination of the neck can reduce the risk of complications related to vessel anatomical variants. When the tracheostomy is complicated by bleeding, the procedure should be stopped in order to diagnose the vascular iatrogenic injury and to evaluate the best therapeutic approach by a multidisciplinary team.
