Ketamine does not reduce postoperative morphine consumption after tonsillectomy in children.
Tonsillectomy is one of the most frequently performed operations in children and frequently associated with moderate-to-severe pain. ⋯ The addition of ketamine 0.25 mg/kg at induction of anesthesia did not decrease postoperative morphine consumption in children undergoing tonsillectomy.

Randomized Controlled Trial
Multidisciplinary rehabilitation treatment of patients with chronic low back pain: a prognostic model for its outcome.
(1) To determine if treatment outcome in chronic low back pain can be predicted by a predefined multivariate prognostic model based on consistent predictors from the literature and (2) to explore the value of potentially prognostic factors further. ⋯ The results of this study do not support the construction of a clinical prediction model. Future confirmative studies of homogeneous rehabilitation treatments and outcome measures are needed to shed more light on relevant prognostic factors.
