Randomized Controlled Trial Comparative Study Clinical Trial
Zingiber officinale (ginger)--an antiemetic for day case surgery.
The effect of powdered ginger root was compared with metoclopramide and placebo. In a prospective, randomised, double-blind trial the incidence of postoperative nausea and vomiting was measured in 120 women presenting for elective laparoscopic gynaecological surgery on a day stay basis. The incidence of nausea and vomiting was similar in patients given metoclopramide and ginger (27% and 21%) and less than in those who received placebo (41%). ⋯ The requirements for postoperative analgesia, recovery time and time until discharge were the same in all groups. There was no difference in the incidence of possible side effects such as sedation, abnormal movement, itch and visual disturbance between the three groups. Zingiber officinale is an effective and promising prophylactic antiemetic, which may be especially useful for day case surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
Fibreoptic intubation. Influence of tracheal tube tip design.
A randomised study was carried out in 60 patients to assess the influence of tracheal tube tip design on the ease of railroading a tracheal tube during fibreoptic intubation. A new design of tracheal tube with a tapered tip, without a bevel, was compared with a tracheal tube of standard design. The new design was found to be greatly superior in both oro- and nasotracheal fibreoptic intubation, when compared with the traditional tracheal tube (p < 0.001). The shape of the tip of a tracheal tube is an important determinant of the ease of railroading the tube over an inserted fibrescope.
