Patients with neuropathic pain commonly present with spontaneous pain, in addition to allodynia and hyperalgesia. Although evoked responses in neuropathic pain models are well characterized, determining the presence of spontaneous pain is more challenging. We determined whether the chronic constriction injury (CCI) model could be used to measure effects of treatment of spontaneous pain, by evaluating dorsal horn neuron (DHN) spontaneous activity and spontaneous pain-related behaviors. ⋯ The median rate of spontaneous activity in the CCI group (12.6 impulses per second) was not different from the sham group (9.2 impulses per second). Also, there was no change in DHN spontaneous activity after sciatic nerve block with bupivacaine. Our findings suggest that CCI as a neuropathic pain model should not be used to measure effects of treatment of spontaneous pain driven by the peripheral input.

Multicenter Study Clinical Trial
Cost-effectiveness of Enhanced Recovery Versus Conventional Perioperative Management for Colorectal Surgery.
To determine the cost-effectiveness of enhanced recovery pathways (ERPs) versus conventional care for patients undergoing elective colorectal surgery. ⋯ Enhanced recovery is cost-effective compared with conventional perioperative management for elective colorectal resection.

Randomized Controlled Trial Comparative Study
Tolerability and performance of BIP endotracheal tubes with noble metal alloy coating--a randomized clinical evaluation study.
Hospital acquired infections worsen the outcome of patients treated in intensive care units and are costly. Coatings with silver or metal alloys may reduce or alter the formation of biofilm on invasive medical devices. An endotracheal tube (ETT) is used to connect the patient to a ventilator and coated tubes have been tested in relation to bacterial colonization and respiratory infection. In the present study, we aimed to evaluate and compare a coated and uncoated ETT for patient symptoms and local tracheal tolerability during short term clinical use. Degree of bacterial colonization was also described. ⋯ The new device BIP ETT is well tolerated and has good clinical performance during short-term intubation. Studies with larger sample sizes and longer intubation periods (>24 h) in the ICU-setting are needed and can now be planned in order to identify possible differences in clinical outcomes.

Randomized Controlled Trial
Local Infiltration Analgesia reduces pain and hospital stay after primary TKA : randomized controlled double blind trial.
Postoperative analgesia following Total Knee Arthroplasty (TKA) with the use of parenteral opioids or epidural analgesia can be associated with important side effects. Good perioperative analgesia facilitates faster rehabilitation, improves patient satisfaction, and may reduce the hospital stay. We investigated the analgesic effect of a locally injected mixture of drugs, in a double blinded RCT in 80 primary TKA. ⋯ In addition, they had lower VAS for pain during rest and activity and higher visual analog scores for patient satisfaction 72 hours postoperatively. No major complication related to the drugs was observed. Intraoperative periarticular injection with multimodal drugs following TKA can significantly reduce the postoperative pain and hence the requirements for PCA and hospital stay, with no apparent risks.
