When spinal cord functional integrity is at risk during surgery, intraoperative neuromonitoring is recommended. Tibial Single Trial Somatosensory Evoked Potentials (SEPs) and H-reflex are here used in a combined neuromonitoring method: both signals monitor the spinal cord status, though involving different nervous pathways. However, SEPs express a trial-to-trial variability that is difficult to track because of the intrinsic low signal-to-noise ratio. For this reason single trial techniques are needed to extract SEPs from the background EEG. ⋯ The ARX filter showed good performances in single trial SEP extraction, enhancing the available information concerning the current spinal cord status. Moreover, the comparison between SEPs and H-reflex showed that the two signals are affected by the same surgical maneuvers, even if they monitor the spinal cord through anatomically different pathways.

[Modern inhalational anesthesia in pediatric maxillofacial surgery].
The paper deals with the use of sevoflurane and isoflurane in elective pediatric maxillofacial surgery. Having outlined the major features of anesthesia in this category of patients, the authors emphasize the application of the conception of the minimum alveolar concentration (MAC) and its derivatives (MAC bar and MAC awake) reflecting the analgesic and hypnotic power of an inhalational anesthetic, respectively, and theoretically substantiate the use of certain anesthetic concentrations at particular stages of surgery. The technique described in the paper was used in 82 patients aged 1.5 months to 18 years, undergoing cleft lip and cleft palate repair, residual lip and nose deformation repair, and other elective maxillofacial procedures. ⋯ Hemodynamics was characterized by moderate controlled hypotension with an average decrease in mean blood pressure by 30% of the age-related value. Emergence occurred 5-15 min after an anesthetic was discontinued. By and large, the technique demonstrated its efficiency and safety in this group of patients.

Gabapentin is an antiepileptic drug used in a variety of chronic pain conditions. Increasing numbers of randomized trials indicate that gabapentin is effective as a postoperative analgesic. This procedure-specific systematic review aims to analyse the 24-hour postoperative effect of gabapentin on acute pain in adults. ⋯ Perioperative use of gabapentin has a significant 24-hour opioid sparing effect and improves pain score for both abdominal hysterectomy and spinal surgery. Nausea may be reduced in abdominal hysterectomy.

Randomized Controlled Trial Comparative StudyEffectiveness of computer-navigated minimally invasive total hip surgery compared to conventional total hip arthroplasty: design of a randomized controlled trial.
Moderate to severe osteoarthrosis is the most common indication for Total Hip Arthroplasty (THA). Minimally Invasive Total Hip Surgery (MIS) and computer-navigated surgery were introduced several years ago. However, the literature lacks well-designed studies that provide evidence of superiority of computer-navigated MIS over a conventional THA technique. Hence, the purpose of this study is to compare (cost)effectiveness of computer-navigated MIS with a conventional technique for THA. It is our hypothesis that computer-navigated MIS will lead to a quicker recovery during the early postoperative period (3 months), and to an outcome at least as good 6 months postoperatively. We also hypothesize that computer-navigated MIS leads to fewer perioperative complications and better prosthesis positioning. Furthermore, cost advantages of computer-navigated MIS over conventional THA technique are expected. ⋯ Based on studies performed so far, few objective data quantifying the risks and benefits of computer-navigated MIS are available. Therefore, this study has been designed to compare (cost) effectiveness of computer-navigated MIS with a conventional technique for THA. The results of this trial will be presented as soon as they become available.

Robotic technology is nothing more than an enhancement along the continuum of laparoscopic technological advances and represents only the beginning of numerous more forthcoming advances. It constitutes a major improvement in the efficiency, accuracy, ease, and comfort associated with the performance of laparoscopic operations. ⋯ In our hands, robotic operative times for simple and radical hysterectomy are shorter than those obtained by conventional laparoscopy. Robotic technology is preferable to conventional laparoscopic instrumentation for the surgical treatment of gynecologic malignancies and most operations for benign disease of certain complexity such as hysterectomy myomectomy, and invasive pelvic endometriosis.
