BACKGROUND: Recruitment maneuver and positive end-expiratory pressure (PEEP) can be used to counteract intraoperative anesthesia-induced atelectasis. Variable ventilation can stabilize lung mechanics by avoiding the monotonic tidal volume and protect lung parenchyma as tidal recruitment is encompassed within the tidal volume variability. METHODS: Forty-nine (7 per group) male Wistar rats were anesthetized, paralyzed, and mechanically ventilated. A recruitment maneuver followed by stepwise decremental PEEP titration was performed while continuously estimating respiratory system mechanics using recursive least squares...

Peritoneal dialysis can be performed at home, and the transfer of solutes in the blood and other body fluids is slow compared to hemodialysis, reducing the load on the circulatory organs and lessening the frequency of hospital visits. We encountered a male patient in his 70s on peritoneal dialysis for end-stage renal failure who developed obsolete mandibular fracture-associated pseudarthrosis accompanied by osteomyelitis, which was treated with noninvasive reduction and fixation using circumferential wiring after the resolution of inflammation...

BACKGROUND: Robot-assisted laparoscopic prostatectomy (RALP) requires pneumoperitoneum and the Trendelenburg position to optimize surgical exposure, which can increase intracranial pressure (ICP). Anesthetic agents also influence ICP. We compared the effects of propofol and sevoflurane on sonographic optic nerve sheath diameter (ONSD) as a surrogate for ICP in prostate cancer patients who underwent RALP. METHODS: Thirty-six patients were randomly allocated to groups receiving propofol (propofol group, n = 18) or sevoflurane (sevoflurane group, n = 18) anesthesia...

OBJECTIVES: Neuropeptide Y (NPY) potently suppresses spike-wave discharges (SWDs) in a genetic rat model of absence epilepsy (GAERS), but the underlying neurophysiologic mechanisms are not clear. We therefore sought to determine the in vivo effects of NPY on neuronal firing in the cortico-thalamo-cortical network activity, known to play a critical role in the generation of SWDs in these rats. METHODS: NPY was administered intracerebroventricularly (ICV) or in separate experiments locally on the neurons of caudal thalamic reticular nucleus (NRT) by use of juxtacellular iontophoresis in triple-barrel electrodes in male GAERS aged 12-15 weeks, in vivo under neuroleptic anesthesia...

Background/aim: Alprostadil and iloprost are successful agents used for both pulmonary hypertension and extremity ischemia treatment. Different systemic effects of these agents may change the preferences of clinical usage. Superiority of preventing ischemia/ reperfusion (IR) injury is a criterion for clinical preference of these agents. The present study was designed to compare the protective effects of alprostadil and iloprost in a rat model of IR injury. Materials and methods: Twenty-three male Sprague Dawley rats were used (aged 8-12 weeks, mean weight 230 ± 30 g)...

BACKGROUND: Breast cancer accounts for nearly a quarter of all cancers in women worldwide, and more than 90% of women diagnosed with breast cancer undergo mastectomy or breast-conserving surgery. Retrospective clinical studies have suggested that use of regional anesthesia leads to improved patient outcomes. Laboratory studies have reported that breast cancer cells are inhibited by some local anesthetics at millimolar concentration. Here, we present a comprehensive analysis of the effects of six common local anesthetics on two human breast cancer cell lines...

This article was requested by the Editor, Professor Harald Brevik after listening to a lecture I gave in a similar vein. Harald wanted the information in print and I have done this in a partly autobiographical form to explain how I came to work and learn from both the late John J. Bonica and the late Wilbert Fordyce. Both of these men have been important in different ways to our present pain world. John J. Bonica made many contributions not only in pain but in regional anesthesia and obstetrical anesthesia but not on the same level...

BACKGROUND: The plantaris tendon (PT) has been implicated in the pathogenesis of symptoms in a subset of patients with Achilles region pain syndromes and has been traditionally managed via open surgical resection. Although the PT can be visualized on ultrasound, a minimally invasive technique for sonographically guided PT release has not been formally described. OBJECTIVE: To validate a technique to perform sonographically guided PT release in an unembalmed cadaveric model...

BACKGROUND AND OBJECTIVES: For superficial surgery of anteromedial and posteromedial surfaces of the upper arm, the medial brachial cutaneous nerve (MBCN) and the intercostobrachial nerve (ICBN) must be selectively blocked, in addition to an axillary brachial plexus block. We compared efficacy of ultrasound-guided (USG) versus conventional block of the MBCN and the ICBN. METHODS: Eighty-four patients, undergoing upper limb surgery, were randomized to receive either USG (n = 42) or conventional (n = 42) block of the MBCN and the ICBN with 1% mepivacaine...

Fentanyl is a potent synthetic opioid used as a narcotic analgesic supplement in general and regional anesthesia as well as in management of persistent, severe chronic pain. Alarming epidemiological and forensic medicine reports, accumulated mainly during the last two decades, point to a growing increase in illicit use of fentanyl, mainly in North America and Europe. Toxicological data indicates that fentanyl use is inextricably linked with polydrug use. There are two main sources of fentanyl on the "recreational" drug market...

BACKGROUND: Preeclampsia is among the most common medical complications of pregnancy. The clinical utility of invasive hemodynamic monitoring in preeclampsia (e.g., Swan-Ganz catheter) is controversial. Thoracic impedance cardiography (TIC) and Doppler echocardiography are noninvasive techniques but they both have important limitations. NICaS™ (NI Medical, PetachTikva, Israel) is a noninvasive cardiac system for determining cardiac output (CO) that utilizes regional impedance cardiography (RIC) by noninvasively measuring the impedance signal in the periphery...
