Randomized Controlled Trial Comparative StudyEndotracheal tube size and sore throat following surgery: a randomized-controlled study.
Women experience less frequent and less severe sore throat postoperatively after intubation with a size 6.0 ETT versus size 7.0.

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 StudyLate sensory function after intraoperative capsaicin wound instillation.
Intense capsaicin-induced C-fiber stimulation results in reversible lysis of the nerve soma, thereby making capsaicin wound instillation of potential interest for the treatment of post-operative pain. Clinical histological and short-term sensory studies suggest that the C-fiber function is partly re-established after skin injection of capsaicin. However, no study has evaluated the long-term effects of wound instillation of purified capsaicin on sensory functions. ⋯ This small-volume study calls for further long-term safety studies of wound capsaicin instillation.

Randomized Controlled Trial Comparative StudySparing the larynx during gynecological laparoscopy: a randomized trial comparing the LMA Supreme and the ETT.
We designed a prospective randomized single-blind study to compare efficiency and post-operative upper airway morbidity when the laryngeal mask airway (LMA) Supreme is used as an alternative to the endotracheal tube (ETT). ⋯ We demonstrated that choosing an LMA Supreme was an efficient pharyngolaryngeal morbidity-sparing strategy. Moreover, we showed that the LMA Supreme and the ETT were equally effective airways for a routine gynecological laparoscopy procedure.

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.
