Injuries to the tracheobronchial tree are a well-recognized sequel of massive blunt trauma to the chest, and although unusual, are life threatening. We report a 16-year-old-boy who developed complete disruption of both bronchi after a motor vehicle accident. After induction of general anaesthesia and oral intubation, ventilation could not be maintained, and oxygenation worsened abruptly with peripheral oxygen saturation values less than 60%. Jet ventilation through two intrabronchial catheters, inserted via emergency thoracotomy, raised the saturation from 60% to 100%, and surgery thereafter was straightforward. The anaesthetic management of tracheobronchial repair is discussed.

Background:The aim of this study was to evaluate the analgesic efficacy of pre-operative single dose of intravenous (I.V.) magnesium sulfate infusion in patients undergoing elective Cesarean section.Materials and Methods:Seventy pregnant women who underwent elective Cesarean section were randomly divided into two groups. Before induction of anesthesia, the magnesium group (Group A) received magnesium sulfate 50 mg/kg I.V. in bolus dose. The control group (Group B) received the same volume of isotonic saline. The pain scores at rest and also upon movement were evaluated up to 24 h post-operatively and analgesic requirement was recorded during the first 24 h after operation.Results:Cumulative analgesic consumption (24 h after operation was 11.2 ± 6.3 mg in group A vs. 13.9 ± 3.9 mg in group B). Post-operative pain scores (24 h after operation was 1.8 ± 2.1 in group A vs. 2.9 ± 1.2 in group B) and shivering incidents (8.57 in group A vs. 14.28 in group B) were significantly lower in Group A (P < 0.05). Mean arterial pressure just after intubation and during the immediate post-operative period was significantly lower in Group A (P < 0.05).Conclusion:Pre-operative intravenous magnesium sulfate infusion decrease post-operation pain and requirement of analgesia in Cesarean section.

Background:Post-dural puncture headache (PDPH) is a known complication of neuroaxial anesthesia and may be associated with significant morbidity. As invasive treatment for PDPH has known complications, pharmacologic management may be preferable. The main objective of the present study was to evaluate the effects of combining administration of intravenous aminophylline and dexamethasone on PDPH in patients who underwent lower extremity surgery in comparison with using either drug alone and also comparing them with placebo.Materials and Methods:One hundred and forty patients, aged 20-65 years, scheduled for lower extremity surgery in Alzahra University Hospital under spinal anesthesia were enrolled in this randomized, double-blind, placebo-controlled study. Patients were divided into four groups of 35 each and received aminophylline 1.5 mg/kg i.v. (group A), dexamethasone 0.1 mg/kg (group D), aminophylline 1.5 mg/kg plus dexamethasone 0.1 mg/kg i.v. (group AD), and placebo (group P). The incidences of PDPH and complete response were evaluated at 6-48 h after arrival to the ward in the four groups.Results:Patients in group AD had significantly lower incidence of PDPH (5.88% vs. 20.58% for group A and 17.14% for group D with P < 0.05), the highest incidence of complete response, and also, less analgesic requirement compared with groups A, D, and P throughout 6-48 h (1.2 ± 0.4 vs. 2.3 ± 0.75 for group A, 1.8 ± 0.6 for group D, and 3.3 ± 1 for placebo group with P < 0.05).Conclusion:Combine administration of aminophylline 1.5 mg/kg plus dexamethasone 0.1 mg/kg significantly reduced PDPH better than using either drug alone in patients who underwent lower extremity surgery under spinal anesthesia.

Background:Post-tonsillectomy pain is one of the most common problems after anesthesia, therefore use of a good anesthesia technique with minimum side effect is an important aim. This study was performed to compare the efficacy of peritonsillar infiltration of bupivacaine, tramadol and combination of bupivacaine-tramadol in post-tonsillectomy pain.Materials and Methods:In a double blind trial 120 ASA I and II children condidated for tonsillectomy were randomized into four groups: Peritonsillar infiltration with bupivacaine 1 mg/kg in Group B, tramadol 2 mg/kg in Group T, combination of bupivacaine-tramadol in Group BT and saline in Group C was done.Results:Until 60 minutes in the recovery room, control of pain in the first three groups were better than Group C (P < 0.05) and in the third group it was better than others. Four hours after surgery, control of pain was better in the second and third groups in comparison to Groups B and Group C (P <0.05) and was better in the third group in comparison to the second group. Then, 24 hours after that, only in the group III the control of pain was effective (P < 0.05).Conclusions:In this study we showed that peritonsillar infiltration with combination of bupivacain-tramadol provided less post surgery pain compared with infiltration of bupivacaine and tramadol alone in adenotonsillectomy of children.
