Multicenter Study Clinical Trial
Efficacy and tolerability of oxycodone hydrochloride controlled-release tablets in moderate to severe cancer pain.
Oxycodone is a semisynthetic opioid analgesic drug classed as a strong opioid. The controlled-release oxycodone tablet formulation (OCRT) was approved in China in 2004 for management of moderate to severe cancer pain. Few data about the efficacy of OCRT and clinical outcomes in Chinese patients taking this drug are available. The purpose of this study was to evaluate the efficacy and tolerability of this drug for relief of moderate to severe cancer pain in Chinese patients. ⋯ We conclude that OCRT is well tolerated and effective in controlling moderate to severe cancer pain in Chinese patients.

Randomized Controlled Trial
Tramadol in the treatment of neuropathic cancer pain: a double-blind, placebo-controlled study.
To assess the efficacy, safety and impact on quality of life of tramadol in the treatment of neuropathic pain in patients with cancer. ⋯ Tramadol is a therapeutic option for the control of neuropathic pain in patients with cancer, and appears to improve quality of life in these patients. The analgesic effect of tramadol is independent of changes in anxiety, depression and nervous system function.

Randomized Controlled Trial Comparative Study
Effects of esmolol, lidocaine and fentanyl on haemodynamic responses to endotracheal intubation: a comparative study.
Predicting the haemodynamic changes that may result in myocardial ischaemia for patients undergoing laryngoscopy and tracheal intubation will help to avoid events that trigger ischaemia and allow immediate treatment. The objective of this study was to compare the effects of esmolol with those of lidocaine (lignocaine) and fentanyl on prevention of tachycardia and hypertension caused by endotracheal intubation. ⋯ It can be concluded that administration of esmolol 1.5 mg/kg 2 minutes before intubation prevents tachycardia and an increase in RPP caused by laryngoscopy and tracheal intubation, and can be beneficial when administered before laryngoscopy and tracheal intubation in patients with tachycardia.

Multicenter Study
Absorption of fentanyl from fentanyl buccal tablet in cancer patients with or without oral mucositis: a pilot study.
Patients with cancer, particularly those undergoing chemotherapy or radiotherapy, may develop oral mucositis. This is the first study to investigate the absorption profile of fentanyl buccal tablet (FBT) - an effervescent formulation of fentanyl indicated for the management of breakthrough pain in opioid-tolerant cancer patients - in patients with or without oral mucositis. ⋯ The absorption profile of a single dose of FBT 200 microg was similar in patients with or without mild oral mucositis. The compound was generally well tolerated.

Randomized Controlled Trial
A combination of lidocaine (lignocaine) and remifentanil reduces pain during propofol injection.
Pain on injection is a well known adverse effect of propofol. The purpose of this study was to compare the analgesic effect of a lidocaine (lignocaine)/remifentanil combination compared with either lidocaine alone or remifentanil alone during propofol injection for induction of anaesthesia. ⋯ Pretreatment with a combination of lidocaine and remifentanil is more effective than either pretreatment alone in reducing pain on injection of propofol.
