Randomized Controlled Trial
Ketamine for treatment of catheter related bladder discomfort: a prospective, randomized, placebo controlled and double blind study.
Intraoperative urinary catheterization might cause postoperative catheter related bladder discomfort (CRBD). We evaluated the efficacy of ketamine as a treatment modality for CRBD. ⋯ I.V. ketamine (250 microg kg(-1)) is an effective treatment for reducing the incidence and severity of postoperative CRBD.

Randomized Controlled Trial
Efficacy of aminocaproic, tranexamic acids in the control of bleeding during total knee replacement: a randomized clinical trial.
Risks and costs of allogeneic blood transfusions mandate strategies to reduce blood loss in surgery. The objective of this study was to assess the efficacy of antifibrinolytic treatment in reducing perioperative blood loss during total knee replacement. ⋯ Antifibrinolytic agents produce a significant decrease in blood loss in patients undergoing total knee replacement, reflected in a reduction in the number of blood transfusions required.

In high-risk industries such as aviation, the skills not related directly to technical expertise, but crucial for maintaining safety (e.g. teamwork), have been categorized as non-technical skills. Recently, research in anaesthesia has identified and developed a taxonomy of the non-technical skills requisite for safety in the operating theatre. Although many of the principles related to performance and safety within anaesthesia are relevant to the intensive care unit (ICU), relatively little research has been done to identify the non-technical skills required for safe practice within the ICU. ⋯ However, the ICU presents a range of unique challenges to practitioners working within it. It is therefore necessary to conduct further non-technical skills research, using human factors techniques such as root-cause analyses, observation of behaviour, attitudinal surveys, studies of cognition, and structured interviews to develop a better understanding of the non-technical skills important for safety within the ICU. Examples of such research highlight the utility of these techniques.

Randomized Controlled Trial Comparative Study
Propofol-alfentanil vs propofol-remifentanil for posterior spinal fusion including wake-up test.
Wake-up test can be used during posterior spinal fusion (PSF) to ensure that spinal function remains intact. This study aims at assessing the characteristics of the wake-up test during propofol-alfentanil (PA) vs propofol-remifentanil (PR) infusions for PSF surgery. ⋯ Wake-up test can be conducted faster with remifentanil compared with alfentanil infusion during PSF surgery.

Superimposed high-frequency jet ventilation (SHFJV), which does not require any tracheal tubes or catheters, was developed specifically for use in laryngotracheal surgery. SHFJV uses two jet streams with different frequencies simultaneously and is applied in the supraglottic space using a jet laryngoscope and jet ventilator. ⋯ SHFJV is an advanced ventilation mode playing a pivotal role in the (open) ventilatory support/ventilation of patients with laryngotracheal stenosis. It is particularly indicated in cases of severe stenosis and offers optimal conditions for laryngotracheal surgery, including laser surgery and stent implantation techniques.
