Randomized Controlled TrialA preoperative single dose of methadone for moderate-to-severely painful surgery reduces postoperative morphine consumption.
Data from patient questionnaires reveal that the intensity of postoperative pain is widely underestimated. Insufficient pain control may contribute to impaired short- and long-term outcome. Preoperative administration of methadone might potentially improve postoperative pain control due to its long pharmacological half-life. ⋯ A single dose of methadone administered at anesthesia induction prior to moderate-to-severely painful surgery is a possible strategy to reduce postoperative morphine consumption.

ReviewDiving physiopathology: the end of certainties? Food for thought.
Our understanding of decompression physiopathology has slowly improved during this last decade and some uncertainties have disappeared. A better understanding of anatomy and functional aspects of patent foramen ovale (PFO) have slowly resulted in a more liberal approach toward the medical fitness to dive for those bearing a PFO. Circulating vascular gas emboli (VGE) are considered the key actors in development of decompression sickness and can be considered as markers of decompression stress indicating induction of pathophysiological processes not necessarily leading to occurrence of disease symptoms. ⋯ Finally, the role of the "normobaric oxygen paradox" has been clarified and it is not surprising that it could be involved in neuroprotection and cardioprotection. However, the best level of inspired oxygen and the exact time frame to achieve optimal effect is still not known. The aim of this paper was to reflect upon the most actual uncertainties and distil out of them a coherent, balanced advice towards the researchers involved in gas-bubbles-related pathologies.

ReviewThe pearls of pediatric sedation: polish the old and embrace the new.
Over the past decade, as the complexity and breadth of pediatric procedures increases, the actual choices of approved sedatives have remained relatively stagnant. Since the introduction of midazolam, there has not been a sedative approved for pediatric labelling until December 2018. This December, the European approval of ADV6209 (Ozalin) for pediatric usage marked the newest addition to the pediatric sedative armamentarium in over a decade. This review is timely and significant because it will provide a balanced evaluation of the most common sedatives in use today, the most recent sedative to be approved and, most importantly, a critical look at the literature supporting the latest approaches to the most commonly performed procedures.

Clinical TrialBody Mass Index does not affect intraoperative goal-directed fluid requirements.
Perioperative normovolemia is a major determinant of tissue oxygen availability and postoperative outcome. Thus, adequate volume replacement therapy remains an essential part of perioperative management. Nevertheless, volume optimization in overweight and obese surgical patients with alterations in cardiovascular function, peripheral perfusion, and body composition remains challenging. We, therefore, tested the hypothesis that Body Mass Index (BMI) correlates with fluid requirements during goal-directed management. Furthermore, we evaluated subcutaneous tissue oxygen tension (PsqO2) as an indicator of intravascular volume status and peripheral perfusion. ⋯ BMI did not affect intraoperative fluid requirements. Doppler-guided intravascular volume optimization was associated with well-maintained subcutaneous tissue oxygen availability in all BMI groups.

ReviewRegional analgesia techniques for pain management in patients admitted to the intensive care unit.
Controlling pain should be a priority in the clinical practice of intensive care units (ICUs). Monomodal analgesic approaches, such as the administration of opioids, are widely employed; however, the widespread use of opioids has catastrophic consequences, given their multiple side effects and the development of dependence. Regional analgesia (RA), with single or continuous dosing using neuraxial and peripheral catheters, can play an important role in multimodal analgesia for management of pain in critical care patients. ⋯ Many critically ill, post-surgical or traumatically injured patients would benefit from these techniques. For these reasons, we aim to establish a set of potential indications integrating the use of RA in analgesia protocols routinely used in ICUs. We performed a review of literature sources with contrasted evidence levels to present RA techniques and their potential applications in ICU patients.
