Case ReportsUse of neuromuscular monitoring to detect prolonged effect of succinylcholine or mivacurium: three case reports.
Mutations in the butyrylcholinesterase gene can lead to a prolonged effect of the neuromuscular blocking agents, succinylcholine and mivacurium. If the anaesthesiologist is not aware of this condition, it may result in insufficient respiration after tracheal extubation. However, this can be avoided with the use of objective neuromuscular monitoring if used adequately. ⋯ Both patients had insufficient respiration. They were therefore re-sedated, transferred to the intensive care unit and the tracheas were extubated after full recovery from neuromuscular blockade. We recommend the use of monitoring every time these agents are used, even with short-acting drugs like succinylcholine and mivacurium.

Controlled Clinical TrialAssessment of deep tissue hyperalgesia in the groin - a method comparison of electrical vs. pressure stimulation.
Deep pain complaints are more frequent than cutaneous in post-surgical patients, and a prevalent finding in quantitative sensory testing studies. However, the preferred assessment method - pressure algometry - is indirect and tissue unspecific, hindering advances in treatment and preventive strategies. Thus, there is a need for development of methods with direct stimulation of suspected hyperalgesic tissues to identify the peripheral origin of nociceptive input. ⋯ The presented tissue-specific direct deep tissue electrical stimulation technique has equal or superior reliability compared with the indirect tissue-unspecific stimulation by pressure algometry. This method may facilitate advances in mechanism based preventive and treatment strategies in acute and chronic post-surgical pain states.

Randomized Controlled Trial Comparative StudyThe influence of glucose load on metabolism during minor surgery using remifentanil-induced anesthesia.
During perioperative fasting, lipid metabolism gradually increases, resulting in free fatty acids (FFA) and/or ketone bodies. Suppression of surgical stress by remifentanil may allow the safe administration of glucose infusions, avoiding both hyperglycemia and ketogenesis. The effects of glucose infusion on glucose and lipid metabolism were therefore investigated in patients undergoing minor surgery with remifentanil anesthesia. ⋯ Infusion of low-dose glucose attenuated fat catabolism without causing hyperglycemia, indicating that infusion of low-dose glucose during remifentanil-induced anesthesia may be safe for patients.

Randomized Controlled TrialDexmedetomidine does not reduce emergence agitation in adults following orthognathic surgery.
Patients undergoing orthognathic surgery are at high risk of developing emergence agitation. We hypothesised that a single-dose of dexmedetomidine would reduce emergence agitation in adults with nasotracheal intubation after orthognathic surgery. ⋯ The addition of a single dose of dexmedetomidine (1 μg/kg) to low-dose remifentanil infusion did not attenuate emergence agitation in intubated patients after orthognathic surgery compared with low-dose remifentanil infusion alone. However, single-dose dexmedetomidine suppressed coughing, haemodynamic changes, and pain during emergence and recovery phases, without respiratory depression. Delayed awakening might be associated with this treatment.

Impact of malnutrition on propofol consumption and recovery time among patients undergoing laparoscopic gastrointestinal surgery.
Malnutrition is a major health problem, especially in hospitalized patients as it can be closely related to many post-operative complications. However, research on malnutrition and its effect on the outcome of general anesthesia have been largely neglected. Here we investigated malnutrition status on propofol consumption and recovery time among patients undergoing laparoscopic gastrointestinal surgery under general anesthesia. ⋯ The present results indicate that the dosage and recovery time of propofol does change in malnourished individuals. Therefore, malnutrition may somehow affect the outcome of general anesthesia.
