Background: Prolonged postoperative mechanical ventilation after intracranial surgery is associated with significant morbidity and mortality. Many traditional tools could help in prediction of weaning success as blood gas analysis (ABG), chest radiography, ventilator parameters and rapid shallow breathing index (RSBI). These tools have a significantly higher failure rate. The aim of this study was to describe the role of transthoracic lung ultrasound (LUS) as a clinical tool in predicting weaning of postoperative mechanically ventilated patients after intracranial surgery. Patients and method:130 patients who were scheduled for weaning from mechanical ventilation (MV), were prospectively enrolled in the study, age 20-70 years, of either sex. They were randomly allocated into two groups-group C (n=65) were examined by traditional methods chest X-ray, ABG, ventilator parameters and RSBI, and group US (n=65) were examined by traditional methods plus LUS. Diaphragm thickness (DT) and fraction (DTF), lung aeration and extravascular lung water (EVLW) were assessed by LUS. A failure of weaning was considered when reintubation was needed within 48 hours. Results: The success rate in group US (LUS+ traditional methods) was 84.6% compared to 66.2% in group C (traditional methods only). The value of diaphragm thickness and fraction were significantly more in the weaning success group than in failure group. B-lines detected by LUS in success and failure groups were ≤2, 3 respectively with no significant difference. Conclusion: Lung ultrasound as an added tool could decrease failure rate of weaning in postoperative mechanically ventilated patients after intracranial surgery.

After removal of artefacts, the mean monitoring time was 22 h08 (8 h54). All patients had impaired cerebral autoregulation during their monitoring time. The mean IAR index was 17 (9.5) %. During H 0 H 6 and H 18 H 24 , the majority of our patients; respectively 53 and 71 % had an IAR index > 10 %. Conclusion According to our data, patients with septic shock had impaired cerebral autoregulation within the first 24 hours of their admission in the ICU. In our patients, we described a variability of distribution of impaired autoregulation according to time. ReferencesSchramm P, Klein KU, Falkenberg L, et al.

Background: Spinal anesthesia is the commonest technique used in Cesarean Section (CS) and most frequently associated with maternal hypotension, for which a lot of techniques have been described to prevent but an effective method is yet to be found. Objectives; The aim was to study the effect of using a sub-anesthetic dose of ketamine to prevent post-spinal hypotension in CS delivery. Methods: This double-blinded randomized controlled study was conducted on 80 participating parturients who were ASA І, П term pregnant. All the parturients received spinal anesthesia. The parturients were then randomly divided into two equal groups (n= 40 in each); ketamine group received a sub-anesthetic dose of ketamine of 0.5 mg/kg IV bolus in 3 ml saline and control group received the same volume of normal saline IV bolus. Heart Rate (HR) and Mean Arterial blood Pressure (MAP) were recorded at baseline (5 minutes prior to the intrathecal injection), at 5, 10, 15 and 20 minutes after the injection and then every 15 minutes till the end of the operation. Incidences of hypotension and severe hypotension were recorded. The total dose of ephedrine was recorded. Ramsay sedation score was recorded at baseline then 5, 10, 15, 30, 45 minutes after injection and then at the end of the operation. Results: Compared to the control group, sedation score was significantly higher among ketamine group at 5, 10 and 15 minutes. MAP and HR were significantly higher among ketamine group at 5, 10, 15, and 20 minutes. Total ephedrine dose was significantly lower among the ketamine group. Mild hypotension and severe hypotension were significantly less frequent among the ketamine group, as all the patients in the control group had an attack of mild hypotension and 55% of this group had an attack of severe hypotension. No significant difference between both the groups regarding diplopia, nystagmus, hallucination, nausea and vomiting. Conclusion: It is concluded that ketamine in a sub-anesthetic dose is an effective agent that can be used in preventing post-spinal hypotension in parturients undergoing CS delivery.
Background Ultrasound (US)-guided quadratus lumborum block (QLB) and transversus abdominis plane block (TAP) are used as a part of multimodal analgesia for postoperative pain after abdominal procedures, as they improve postoperative pain. Results QLB group showed significantly better visual analog score (VAS) scores from 6 h till 24 h postoperative. Time for the first request for pethidine was significantly longer in the QLB group (398.3 ± 23.7 min) than in the TAP group (80.3 ± 20.7 min), (p < 0.0001 and its total consumption was significantly lesser (p = 0.007) in the QLB group (68.33 ± 66.28) than in TAP group (120.0 ± 76.11). Also, the sensory level was higher in the QLB group (8.3 ± 0.63 segments) than in the TAP group (6.2 ± 0.79 segments), (p < 0.001). Moreover, only 2 patients (6.67%) in the QLB group experienced nausea and/or vomiting versus 9 (30%) in TAP group with significant value. Conclusions QLB was more effective in providing visceral and somatic pain analgesia after total abdominal hysterectomy (TAH) in comparison to TAP block, QLB resulted in wider sensory blockade compared to TAP block with less incidence of postoperative nausea and/or vomiting.
