Clinical Trial
Modified nasal cannula for simultaneous oxygen delivery and end-tidal CO2 monitoring during spontaneous breathing.
Supplemental oxygen is commonly given via nasal cannulae in spontaneously breathing patients. Our modified nasal cannula with a clamp between the nasal prongs can provide O2 via one nostril and CO2 can be sampled through the other one. We have studied whether this cannula can provide oxygenation similar to a standard cannula without affecting end-tidal CO2 monitoring. ⋯ Our modified nasal cannula can provide continuous monitoring of end-tidal CO2 without affecting oxygen delivery in sedated, spontaneously breathing patients.

Preoperative anxiety is a challenging concept in the preoperative care of patients. The hypothesis of this study was that the doctors are able to estimate their patients' preoperative anxiety. ⋯ Both anaesthetists and surgeons overestimated their patients' preoperative anxiety by a wide margin and poorly predicted their patients' feared conditions and their desire for relief of anxiety.

Randomized Controlled Trial
Dexmedetomidine and meperidine prevent postanaesthetic shivering.
This placebo-controlled study was performed to evaluate the efficacy of dexmedetomidine compared with meperidine and placebo in preventing postanaesthetic shivering. ⋯ Intraoperative intravenously administration of dexmedetomidine 1 microg kg(-1) reduces postanaesthetic shivering as does meperidine 0.5 mg kg(-1) in patients after major surgery.

Randomized Controlled Trial
Gabapentin attenuates late but not acute pain after abdominal hysterectomy.
Gabapentin has been suggested to decrease acute postoperative pain. We evaluated the effect of gabapentin on pain after abdominal hysterectomy. ⋯ Gabapentin has no effect on immediate pain after abdominal hysterectomy but decreases pain 1 month postoperatively.

Randomized Controlled Trial Comparative Study
Comparison of face masks in the bag-mask ventilation of a manikin.
We conducted a study investigating the effectiveness of four face mask designs in the bag-mask ventilation of a special manikin adapted to simulate a difficult airway. ⋯ There was a large variation in both performance and satisfaction between anaesthetists with each design. This highlights the importance of having a variety of face masks available for emergency use.
