Randomized Controlled Trial Comparative StudyPostoperative pain after bupivacaine supplementation in mandibular third molar surgery: splint-mouth randomized double blind controlled clinical trial.
Efficacy of anesthetic supplementation with bupivacaine to control both pain and the number of analgesics ingested after surgery has been proposed; however, no report was found in the literature regarding supplemental use of bupivacaine. Thus, the aim of this study was to evaluate the clinical efficacy of bupivacaine in appeasing postoperative pain, when used as supplemental anesthesia at the end of surgeries to extract mandibular third molars. ⋯ There is no appreciable value to the second injection regarding pain and analgesia use, but there was a difference regarding patient acceptance in surgeries of mandibular semi-enclosed and impacted third molars.

Awake endotracheal retrograde intubation in restricted mouth opening: a 'J'-tipped guide wire technique--a retrospective study.
Airway management in patient with restricted mouth opening is a great challenge, owing to the difficulty in laryngoscopy and visualisation of the vocal cords during the procedure of intubation. The term retrograde intubation refers to a technique in which a guide wire is passed into the trachea and then into the mouth or nose. A tracheal tube is then passed down over the guide until it enters the trachea. ⋯ Retrograde tracheal intubation was easy to perform and had a high success rate and a low incidence of complications.

Randomized Controlled Trial Comparative StudyEffects of intra-space injection of Twin mix versus intraoral-submucosal, intramuscular, intravenous and per-oral administration of dexamethasone on post-operative sequelae after mandibular impacted third molar surgery: a preliminary clinical comparative study.
A prospective randomised double-blind study was undertaken to compare the effects of intra-space injection of 'Twin mix' versus intraoral-submucosal, intramuscular, intravenous and per-oral administration of dexamethasone on post-operative sequelae after mandibular impacted third molar surgery. ⋯ Steroid groups had a better clinical outcome with improved quality of life post-operatively when compared to the nonsteroid study group. Intra-space injection of dexamethasone in pterigomandibular space as Twin mix was found to have similar clinical effects as conventional methods of administering steroids via intraoral-submucosal, intramuscular, intravenous and per-oral routes. This, however, is a small study which would now benefit from larger numbers.

Randomized Controlled Trial Comparative StudyA prospective randomized double-blind study to assess the latency and efficacy of twin-mix and 2% lignocaine with 1:200,000 epinephrine in surgical removal of impacted mandibular third molars: a pilot study.
A prospective randomized double-blind study was conducted to assess the latency and duration of pterygomandibular nerve block with a mixture of 1.8 ml 2% lignocaine with 1:200,000 epinephrine and 1 ml of 4 mg dexamethasone and its impact on postoperative sequelae of surgical extraction of impacted mandibular third molars. ⋯ The addition of dexamethasone to lignocaine and its administration as an intra-space injection significantly shortens the latency and prolongs the duration of the soft tissue anesthesia, with improved quality of life in the postoperative period after surgical extraction of mandibular third molars.

Comparative StudyEvaluation of pressure-controlled ventilation concepts during cardiopulmonary resuscitation (CPR) in dental chairs.
Infrequent training of lay rescuers in cardiopulmonary resuscitation may lead to stomach inflation during ventilation of the unsecured airway. This is caused by a pressure loss of the lower oesophageal sphincter (LOSP) after onset of cardiac arrest. To minimise the risk of stomach inflation, the SMART BAG® (SB), a disposable flow-limited bag-valve-mask resuscitator, has been designed. Aim The aim of this study was to evaluate the occurrence of stomach inflation by use of SB in comparison to two other ventilation devices with respect to the ventilation capability. ⋯ Even in the worst case scenario, use of SB and EG/R administered sufficient tidal volumes with a significantly smaller stomach inflation compared to EG. Combination of standard bag-valve devices with a reservoir bag may provide similar protection from gastric inflation as the SMART BAG®.
