[Effect of nitrous oxide on fentanyl consumption in burned patients undergoing dressing change].
Thermal injuries and injured areas management are important causes of pain in burned patients, requiring that these patients are constantly undergoing general anesthesia for dressing change. Nitrous oxide (N2O) has analgesic and sedative properties; it is easy to use and widely available. Thus, the aim of this study was to evaluate the analgesic effect of N2O combined with fentanyl in burned patients during dressing change. ⋯ The association of N2O was not effective in reducing opioid consumption during dressing changes.

[Lumbar spinal anesthesia with cervical nociceptive blockade. Critical review of a series of 1,330 procedures].
The manufacture of minimally traumatic needles and synthesis of pharmacological adjuncts with safe and effective action on inhibitory and neuromodulatory synapses distributed along the nociceptive pathways were crucial for a new expansion phase of spinal anesthesia. The objectives of this paper are present our clinical experience with 1,330 lumbar spinal anesthesia performed with purposeful nociceptive blockade of the thoracic and cervical spinal nerves corresponding to dermatomes C4 or C3; warn about the method pathophysiological risks, and emphasize preventive standards for the safe application of the technique. ⋯ Spinal anesthesia with nociceptive blockade to dermatome C4, or C3, is an effective option for surgery on somatic structures distal to the metamer of the third cervical spinal nerve, lasting no more than four or five hours. The method safety depends on the unrestricted respect for the essential rules of proper anesthesia.

[A randomised comparative study of the effect of Airtraq optical laryngoscope vs. Macintosh laryngoscope on intraocular pressure in non-ophthalmic surgery].
We compared intraocular pressure changes following laryngoscopy and intubation with conventional Macintosh blade and Airtraq optical laryngoscope. ⋯ We conclude that Airtraq laryngoscope in comparison to Macintosh laryngoscope results in significantly fewer rises in intraocular pressure and clinically less marked increase in haemodynamic response to laryngoscopy and intubation.

[Effects of a novel method of anesthesia combining propofol and volatile anesthesia on the incidence of postoperative nausea and vomiting in patients undergoing laparoscopic gynecological surgery].
We investigated the effects of a novel method of anesthesia combining propofol and volatile anesthesia on the incidence of postoperative nausea and vomiting in patients undergoing laparoscopic gynecological surgery. ⋯ Combined propofol and volatile anesthesia during laparoscopic gynecological surgery effectively decreases the incidence of postoperative nausea.

[Sphenopalatine ganglion pulsed radiofrequency treatment in patients suffering from chronic face and head pain.]
There are various facial pain syndromes including trigeminal neuralgia, trigeminal neuropathic pain and atypical facial pain syndromes. Effectiveness of the pulsed radiofrequency in managing various pain syndromes has been clearly demonstrated. There are a limited number of studies on the pulsed radiofrequency treatment for sphenopalatine ganglion in patients suffering from face and head pain. The purpose of this study is to evaluate the satisfaction of pulsed radiofrequency treatment at our patients retrospectively. ⋯ Pulsed radiofrequency of the sphenopalatine ganglion is effective in treating the patients suffering from intractable chronic facial and head pain as shown by our findings. There is a need for prospective, randomized, controlled trials in order to confirm the efficacy and safety of this new treatment modality in chronic head and face pain.
