Pain associated with laparoscopic cholecystectomy is most severe during the first 24 h and the port sites are the most painful. Recent multimodal approaches target incisional pain instead of visceral pain which has led to the emergence of abdominal fascial plane blocks. This study embraces a novel combination of two independently effective fascial plane blocks, namely rectus sheath block and subcostal transversus abdominis plane (TAP) block to alleviate postoperative pain. ⋯ Ultrasound-guided combined fascial plane blocks is a novel intervention in pain management of patients undergoing laparoscopic cholecystectomy and should become the standard of care.

Video laryngoscope-aided intubations require less force to align oral, pharyngeal, and laryngeal planes to visualize the glottis opening during intubation. ⋯ C-MAC video laryngoscope-aided intubations using D-blade significantly reduced the incidence and severity of POST, hoarseness of voice, and cough following orotracheal intubation as compared to use of traditional Macintosh laryngoscope.

The aim is to compare the clinical effect of three different concentrations of levobupivacaine (0.25%, 0.125%, and 0.0625%) on the sensory and motor block characteristics and mode of delivery during epidural labor analgesia. We also studied the pharmacokinetic profile of the three concentrations during labor. ⋯ levobupivacaine concentration of 0.125% is superior to other concentrations for epidural labor analgesia as it provides adequate analgesia without motor affection which reflects in a lower incidence of instrumental delivery or cesarean section.

Awake fiberoptic intubation (AFOI) is a recommended technique for anticipated difficult airway. An ideal regime should provide patient comfort, cooperation, amnesia, hemodynamic stability, and blunt airway reflexes and maintain a patent airway with spontaneous ventilation. The aim of our study was to compare intubation conditions between dexmedetomidine and fentanyl-midazolam combination during AFOI. ⋯ Dexmedetomidine is more effective than midazolam-fentanyl during AFOI, as it provides better intubation condition, hemodynamic stability, and preservation of airway and spontaneous ventilation.

Positive end-expiratory pressure (PEEP) at the time of induction increases oxygenation by preventing lung atelectasis. However, PEEP may not prove beneficial in all cases. Factors affecting the action of PEEP have not been elucidated well and remain controversial. Pulmonary vasculature has direct bearing on the action of PEEP as has been proven in the previous studies. Thus, this prospective study was planned to evaluate the action of PEEP on the basis of pulmonary artery systolic pressure (PASP) which is noninvasive and easily measured by transthoracic echocardiography. ⋯ Morbidly obese patients who have PASP >30 mm Hg benefit most from the PEEP. Thus, PASP which is an easily measurable noninvasive parameter can be used as a criterion for selecting patients who benefit from PEEP application.
