Randomized Controlled Trial Comparative StudyCorrelation and agreement between the bispectral index vs. state entropy during hypothermic cardio-pulmonary bypass.
The bispectral index (BIS) and spectral entropy enable monitoring the depth of anaesthesia. Mild hypothermia has been shown to affect the ability of electroencephalography monitors to reflect the anaesthetic drug effect. The purpose of this study was to investigate the effect of hypothermia during a cardio-pulmonary bypass on the correlation and agreement between the BIS and entropy variables compared with normothermic conditions. ⋯ Acceptable agreement was observed between the BIS and entropy variables under normothermic but not under hypothermic conditions. The BIS and entropy variables may therefore not be interchangeable during a hypothermic cardio-pulmonary bypass.

Randomized Controlled Trial Comparative StudyModafinil reduces patient-reported tiredness after sedation/analgesia but does not improve patient psychomotor skills.
Early recovery of patients following sedation/analgesia and anesthesia is important in ambulatory practice. The aim of this study was to assess whether modafinil, used for the treatment of narcolepsy, improves recovery following sedation/analgesia. ⋯ Modafinil reduces patient-reported tiredness after sedation/analgesia but does not improve recovery in terms of objective measures of patient psychomotor skills.

Randomized Controlled Trial Comparative StudyUnilateral paravertebral block: an alternative to conventional spinal anaesthesia for inguinal hernia repair.
Inguinal herniorrhaphy can be successfully performed using general, regional or local anaesthesia. Paravertebral block (PVB) has been used for unilateral procedures such as thoracotomy, breast surgery, chest wall trauma, hernia repair or renal surgery. ⋯ It can be concluded that unilateral PVB is more efficacious than conventional SA in terms of prolonging post-operative analgesia and reducing morbidities in patients undergoing elective unilateral inguinal hernia repair.

Randomized Controlled Trial Comparative StudySingle stimulation of the posterior cord is superior to dual nerve stimulation in a coracoid block.
Both multiple injection and single posterior cord injection techniques are associated with extensive anesthesia of the upper limb after an infraclavicular coracoid block (ICB). The main objective of this study was to directly compare the efficacy of both techniques in terms of the rates of completely anesthetizing cutaneous nerves below the elbow. ⋯ Injection of a local anesthetic after a single stimulation of the radial nerve fibers produced more extensive anesthesia than using a dual stimulation technique under the conditions of our study.

Implementing a pre-operative checklist to increase patient safety: a 1-year follow-up of personnel attitudes.
The operating room is a complex work environment with a high potential for adverse events. Protocols for perioperative verification processes have increasingly been recommended by professional organizations during the last few years. We assessed personnel attitudes to a pre-operative checklist ('time out') immediately before start of the operative procedure. ⋯ Staff attitudes toward a surgical checklist were mostly positive 1 year after their introduction in two large hospitals in central Sweden.
