Can transcutaneous near infrared spectroscopy detect severe hepatic ischemia: a juvenile porcine model.
Vascular complications following pediatric liver transplantation occur in 8-10% of cases, and no continuous, non-invasive monitoring for this problem exists. Near infrared spectroscopy (NIRS) allows non-invasive, continuous, transcutaneous assessment of hemoglobin oxygenation (StO2 ) 1-4 cm below the skin surface. ⋯ Transcutaneous hepatic StO2 monitoring cannot reliably detect severe hepatic ischemia in a juvenile porcine model, although a stronger and potentially useful signal is seen in 5-7 kg pigs. Trials of this technology should be currently restricted to situations where the organ is less than 1 cm from the skin surface, corresponding to infants of <10 kg.

Randomized Controlled TrialPatient-controlled bolus femoral nerve block after knee arthroplasty: quadriceps recovery, analgesia, local anesthetic consumption.
Continuous femoral nerve block (cFNB) induces quadriceps muscle weakness, but patient-controlled femoral nerve block (PCFNB) can provide analgesia with lower consumption of local anesthetics compared to cFNB. We hypothesized that cFNB followed by PCFNB leads to accelerated recovery of quadriceps weakness after total knee arthroplasty compared to cFNB alone. Secondary outcomes were local anesthetic consumption, pain, and mobilization. ⋯ Continuous femoral nerve block followed by PCFNB does not improve quadriceps strength recovery time compared to cFNB alone after total knee arthroplasty, but similar analgesic effects were demonstrated with reduced levobupivacaine consumption.

Transforaminal percutaneous endoscopic lumbar discectomy (tPELD) poses great challenges for junior surgeons. Beginners often require repeated attempts using fluoroscopy causing more punctures, which may significantly undermine their confidence and increase the radiation exposure to medical staff and patients. Moreover, the impact of an accurate location on the learning curve of tPELD has not been defined. ⋯ The accurate preoperative location method lowered the learning difficulty and reduced the fluoroscopy time of tPELD, which was also associated with lower preoperative location time and puncture-channel time. Key words: Learning difficulty, fluoroscopy reduction, transforamimal percutaneous endoscopic lumbar discectomy, preoperative locationLearning difficulty, fluoroscopy reduction, transforamimal percutaneous endoscopic lumbar discectomy, preoperative location.

Morphine and other opioids are routinely used systemically and as wound infusions in the postoperative period. Their effect on wound and fracture healing remains unclear. ⋯ Cytotoxic effects of morphine are exposure, time and concentration dependent. Simulating aspects of inflammatory conditions seems to increase resistance to morphine cytotoxicity especially in the presence of higher concentration and longer exposure times.

Randomized Controlled TrialTransversus abdominis plane block or intravenous lignocaine in open prostate surgery: a randomized controlled trial.
Transversus abdominis plane block (TAP) and intravenous lignocaine are two analgesic techniques frequently used after abdominal surgery. We hypothesized that these two techniques improve post-operative analgesia after open prostate surgery and sought to compare their efficacy on immediate post-operative outcome after open prostate surgery. ⋯ Our study suggests that TAP block and intravenous lignocaine do not improve the post-operative analgesia provided by systematic administration of paracetamol after open prostatectomy.
