Randomized Controlled Trial Comparative Study
Comparison of intravenous lidocaine versus morphine in alleviating pain in patients with critical limb ischaemia.
Numerous drugs have been proposed to alleviate ischaemic limb pain, but none have been successful in relieving ischaemic pain thoroughly and rapidly. ⋯ Lidocaine may be helpful in decreasing ischaemic pain in patients with critical limb ischaemia.

Randomized Controlled Trial
Rescuer-limited cardiopulmonary resuscitation as an alternative to 2-min switched CPR in the setting of inhospital cardiac arrest: a randomised cross-over study.
The 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation (CPR) recommend that chest compression be rotated every 2 min to prevent rescuer fatigue. However, the quality of chest compression using 2-min switched CPR tends to decrease rapidly due to rescuer fatigue. We aimed to compare the effectiveness of use of 2-min switched CPR and rescuer-limited CPR (the person performing compressions is allowed to switch with another rescuer prior to 2 min if feeling fatigued) in the setting of inhospital cardiac arrest. ⋯ Rescuer-limited CPR yields a greater number of effective compressions and more consistent quality of CPR than 2-min switched CPR. Rescuer-limited CPR might be a suitable alternative for treating inhospital cardiac arrest.

Randomized Controlled Trial Comparative Study
Efficacy of the jet injector in local anaesthesia for small wound sutures: a randomised clinical trial compared with the needle infiltration technique.
Despite advances in the application of needle free devices in medical procedure, there is a paucity of knowledge on the efficacy of the jet injector for suturing skin wounds. ⋯ The jet injector is an effective device in reducing the pain of the anaesthetic procedure for small facial wounds. However, the remarkably lower pain should be evaluated in light of other parameters, including acceptance and preference of the newly introduced technique.

Randomized Controlled Trial
Ultrasound-guided hematoma block in distal radial fracture reduction: a randomised clinical trial.
We compared the efficacy and safety of ultrasound-guided haematoma block with that of procedural sedation and analgesia in patients with acute distal radial fracture reduction pain control. ⋯ Ultrasound guided haematoma block may be a safe and effective alternative to procedural sedation and analgesia.

Randomized Controlled Trial
ABG needle study: a randomised control study comparing 23G versus 25G needle success and pain scores.
To determine whether a narrower gauge needle used in ABG sampling is associated with lower pain scores and complication rates without increasing the level of difficulty of the procedure. ⋯ There was no significant difference in pain scores experienced by patients undertaking ABG sampling with either a 23G or 25G needle.
