Background: Adequate recovery from neuromuscular block (NMB) is imperative for the patient to have full control of pharyngeal and respiratory muscles. The train-of-4 (TOF) ratio should return to at least 0.90 to exclude potentially clinically significant postoperative residual block.

One theory states that neuromuscular blockade prevents disturbing EMG signals, arousing from the muscles of the forehead, from falsely elevating bispectral index (BIS)-levels. According to the afferentation theory signals generated in muscle stretch receptors, accessing the brain through afferent nerve pathways, induce arousal.

This study was aimed to investigate the possible effect of nitrous oxide on the infusion requirements of cisatracurium.
Methods: 70 ASA physical status I-III patients aged 18-75 years were enrolled in this randomized trial.

The presence of endotracheal intubation tube or jet ventilation cannula can compromise free view and access to operation area in certain endolaryngeal operations. The objective of this prospective study was to test whether adequate level of anaesthesia could be obtained in adults using tubeless sevoflurane inhalation anaesthesia with spontaneous breathing. In 23 ASA 1-2 patients, 31 treatments were included in the study of which 19 were laser-assisted papilloma or other tumour resections and 12 were fascia injection laryngoplasties.

Families, whose child was admitted for ambulatory tonsillectomy, participated in the study (n = 116; 58/58).
Background: Children undergoing tonsillectomy have difficulties in postoperative recovery and nutrition.
Objective: The objective of this study was to define how preoperative nutritional face-to-face counseling on child's fasting affects parental knowledge, preoperative need-for-information, and anxiety, in pediatric ambulatory tonsillectomy.
Methods: The participants in the prospective, randomly allocated study were parents (intervention 62/control 62) with children (4-10 years) admitted for ambulatory tonsillectomy. Data were collected by the knowledge test designed for the study and with The Amsterdam preoperative anxiety and information scale (APAIS).

Objective: The aim of this prospective randomized study was to examine whether active counseling and more liberal oral fluid intake decrease postoperative pain, nausea and vomiting in pediatric ambulatory tonsillectomy.
Methods: Families, whose child was admitted for ambulatory tonsillectomy or adenotonsillectomy, were randomly assigned to the study groups (n=116; 58 families in each group). The intervention group received the fasting instructions with face-to-face counseling for the child's active preoperative nutrition, and the control group the fasting instructions according to the hospital's standard procedure.
Background: Nitrous oxide has a minor effect on the effective dose 50% values of bolus doses of rocuronium. The authors have studied the effect of nitrous oxide on the infusion requirements of rocuronium using closed-loop feedback control of rocuronium infusion.
Methods: The authors obtained institutional approval and informed consent to study 70 patients.
Background: Pain following tonsillectomy is often intense. Nonsteroidal anti-inflammatory drugs and opioids are effective, but both can cause adverse effects. Tramadol may be a viable alternative for post-tonsillectomy pain.
