Randomized Controlled Trial Comparative Study Clinical TrialComparison of parenteral diclofenac and ketoprofen for postoperative pain relief after maxillofacial surgery.
Non-steroidal anti-inflammatory drugs (NSAID) effectively reduce the need for opioid analgesia after various types of surgery. The efficacy of diclofenac and ketoprofen to relieve pain after maxillofacial surgery was compared in the present study. In a randomized and double-blind fashion, 90 ASA I-II patients (16-60 yrs) were studied, divided into three groups: Thirty patients received 1.0 mg.kg-1 diclofenac i.v. after general anaesthesia induction, before surgical incision, and four hours later the same dose was given i.m. ⋯ Overall, there was a lower need for i.v. oxycodone during the 24-hour period in the diclofenac group (269 doses) than in the ketoprofen group and in the saline group (388 doses, each) (P < 0.01). The significantly lower number of oxycodone administrations in the diclofenac group was a result of a distinguishable difference, particularly during the first four hours after surgery. There was no statistically significant difference in the incidence of side effects of the analgesic therapy between the three groups.

Randomized Controlled Trial Comparative Study Clinical TrialWound infiltration with ropivacaine and bupivacaine for pain after inguinal herniotomy.
In a double-blind, randomized study, 32 patients scheduled for elective inguinal herniotomy under general anaesthesia received subcutaneous infiltration with 40 ml ropivacaine 2.5 mg/ml or bupivacaine. Postoperative pain intensity was assessed repeatedly for 24 hours at rest, during cough and movement on a visual analogue scale (VAS) and by means of pressure algometry. ⋯ The demand for analgesics was similar in the two groups. We conclude that incisional ropivacaine is as effective as bupivacaine in the management of post-herniotomy pain.

Case ReportsLaryngeal mask airway guided tracheal intubation in a neonate with the Pierre Robin syndrome.
Endotracheal intubation in infants with the Pierre Robin syndrome may sometimes be impossible to accomplish by conventional means. To aid difficult tracheal intubation many different techniques have been described. We present a case, in which we successfully intubated a small-for-date newborn boy with the Pierre Robin syndrome by using a modified laryngeal mask airway (no. 1) as a guide for the endotracheal tube. The technique is easy to perform, less traumatic and less time-consuming than multiple attempts at laryngoscopy or blind tracheal intubation.

Reexpansion of atelectasis during general anaesthesia may have a prolonged effect.
Pulmonary atelectasis, as found during general anaesthesia, may be reexpanded by hyper-inflation of the lungs. The purpose of this study was to determine whether such a recruitment is maintained and whether this is accompanied by an improved gas exchange. We studied a consecutive sample of twelve lung healthy adults, scheduled for elective surgery. ⋯ During general anaesthesia in lung healthy patients, most of the reexpanded atelectatic lung tissue remains inflated for at least 40 min. The recruitment manoeuvre decreases pulmonary shunt, but increases low VA/Q. The net effect on gas exchange is a small reduction of PA-aO2.

Randomized Controlled Trial Comparative Study Clinical TrialControl of post anaesthetic shivering with nefopam hydrochloride in mildly hypothermic patients after neurosurgery.
Postoperative shivering may be prevented by maintaining normothermia intraoperatively or it may be treated using specific drugs. The aim of this study was to compare the efficacy of nefopam hydrochloride (nefopam) to that of clonidine and meperidine in patients undergoing elective neurosurgical procedures. Three groups of patients were included in the study. ⋯ In group B, only 10% of patients receiving nefopam had postoperative shivering, Vo2, VcO2 and EE were significantly lower in patients treated with nefopam than those in the control group. No changes in CSFP, CPP or EEG were observed in group C. In conclusion, nefopam seems to be more effective than clonidine or meperidine in quickly suppressing shivering, without producing significant adverse reactions.
