Quality of recovery after day care surgery with app-controlled remote monitoring: study protocol for a randomized controlled trial.

BACKGROUND: The majority of surgical interventions are performed in day care and patients are discharged after the first critical postoperative period. At home, patients have limited options to contact healthcare providers in the hospital in case of severe pain and nausea. A smartphone application for patients to self-record pain and nausea when at home after day care surgery might improve patient's recovery. Currently patient experiences with smartphone applications are promising; however, we do not know whether remote monitoring with such an application also improves the patient's recovery. This study aims to evaluate the experienced quality of recovery after day care surgery between patients provided with the smartphone application for remote monitoring and patients receiving standard care without remote monitoring. METHODS: This non-blinded randomized controlled trial with mixed methods design will include 310 adult patients scheduled for day care surgery. The intervention group receives the smartphone application with text message function for remote monitoring that enables patients to record pain and nausea. An anaesthesia professional trained in empathetic communication, who will contact the patient in case of severe pain or nausea, performs daily monitoring. The control group receives standard care, with post-discharge verbal and paper instructions. The main study endpoint is the difference in perceived quality of recovery, measured with the QoR-15 questionnaire on the 7th day after day care surgery. Secondary endpoints are the overall score on the Quality of Recovery-15 at day 1, 4 and 7-post discharge, the perceived quality of hospital aftercare and experienced psychological effects of remote monitoring during postoperative recovery from day care surgery. DISCUSSION: This study will investigate if facilitating patients and healthcare professionals with a tool for accessible and empathetic communication might lead to an improved quality of the postoperative recovery period.

Review on pharmacological pain management in trauma patients in (pre-hospital) emergency medicine in the Netherlands.

Pain is one of the main complaints of trauma patients in (pre-hospital) emergency medicine. Significant deficiencies in pain management in emergency medicine have been identified. No evidence-based protocols or guidelines have been developed so far, addressing effectiveness and safety issues, taking the specific circumstances of pain management of trauma patients in the chain of emergency care into account. The aim of this systematic review was to identify effective and safe initial pharmacological pain interventions, available in the Netherlands, for trauma patients with acute pain in the chain of emergency care. Up to December 2011, a systematic search strategy was performed with MeSH terms and free text words, using the bibliographic databases CINAHL, PubMed and Embase. Methodological quality of the articles was assessed using standardized evaluation forms. Of a total of 2328 studies, 25 relevant studies were identified. Paracetamol (both orally and intravenously) and intravenous opioids (morphine and fentanyl) proved to be effective. Non-steroidal anti-inflammatory drugs (NSAIDs) showed mixed results and are not recommended for use in pre-hospital ambulance or (helicopter) emergency medical services [(H)EMS]. These results could be used for the development of recommendations on evidence-based pharmacological pain management and an algorithm to support the provision of adequate (pre-hospital) pain management. Future studies should address analgesic effectiveness and safety of various drugs in (pre-hospital) emergency care. Furthermore, potential innovative routes of administration (e.g., intranasal opioids in adults) need further exploration.

[Ketamine as a party drug]. / Ketamine als partydrug.

Ketamine is a new party drug, which is easy to obtain. For this reason, it is possible that physicians will be increasingly confronted with users that have medical problems. Relatively few cases of ketamine intoxication with a fatal outcome have been reported thus far. Ketamine is very hallucinogenic; people can experience unpleasant flashbacks even weeks after the drug has been eliminated from the body. Ketamine has a short half-life; the elimination half-life is about 2.5 h. A serious intoxication can lead to aspiration, acidosis, rhabdomyolysis, epileptic seizures, respiratory depression, and cardiac arrest. Ketamine is frequently used as a party drug in combination with other substances. As a result, the chance of untoward effects is increased. Anaesthetists use ketamine for short surgical procedures, sedation and analgesia. It is also used more and more often as an analgesic in patients who do not respond well to opioids.

Minimally invasive placement of epidural plate electrodes under local anaesthesia in spinal cord stimulation.

In the treatment of pain syndromes of different aetiologies a change has occurred from destructive interventions to stimulation procedures. Spinal cord stimulation is the best known example of this treatment strategy. It is used often in patients with persistent neuropathic pain syndromes in an extremity, for instance following low back surgery. This treatment is most frequently performed by a percutaneous placement of a single electrode, with the aid of a specially designed Tuohy needle to reach the epidural space. In cases where, for different reasons, a larger, plate electrode is needed, this has to be placed surgically by a small laminectomy. The general anaesthesia mostly needed for this procedure prevents trial stimulation necessary to check the correct electrode position. Besides this, the laminectomy procedure can subsequently result in new pain complaints due to the invasiveness of the procedure. To solve both problems we have modified the implantation technique. By using a tubular retractor system (METRx system, Medtronic Sofamor Danek, Memphis, TN), originally developed for minimally invasive degenerative disc surgery, it is possible to reach the epidural spinal space and introduce the plate electrode with a small approach under local anaesthesia both allowing trial stimulation and avoiding severe postoperative backache related to the approach in these patients.

Long-term intrathecal infusion of morphine and morphine/bupivacaine mixtures in the treatment of cancer pain: a retrospective analysis of 51 cases.

A retrospective analysis of 51 patients with cancer pain treated with a continuous i.t. morphine infusion through a tunnelled percutaneous catheter was undertaken. Because of insufficient pain relief with morphine only, 17 of these patients received a morphine/bupivacaine mixture. Pain relief subsequently improved significantly in 10 patients and a moderate improvement was present in 4 patients. An additional analgesic effect of bupivacaine was not shown in 3 patients with clinical signs of severe mental depression. Bupivacaine-induced side effects were absent below a daily dosage of 30 mg by continuous infusion. In all patients a gradual dose increment was observed. No serious complications, neurologic sequelae or meningitis occurred. It is concluded that long-term i.t. infusion of morphine through a tunnelled catheter can provide adequate pain relief in cancer patients with an acceptable risk-benefit ratio. The effects of long-term intrathecal co-administration of local anesthetics, especially bupivacaine, await further prospective evaluation.
