BACKGROUND AND AIM Obtaining patent airway is a crucial task for many physicians. When opportunities to practice intubations on patients are really limited, skill gaining methods are needed. We conducted a study among novice 6(th) year medical students to assess their ability to intubate the trachea in normal airway in manikin using four airway tools. (More)
BACKGROUND Respiratory function is impaired in obese patients undergoing laparoscopic surgery. This study was performed to determine whether repeated lung recruitment combined with PEEP improves respiratory compliance and arterial partial pressure of oxygen (Pa(O2)) in obese patients undergoing laparoscopic gastric banding. METHODS Sixty patients with BMI(More)
BACKGROUND Dexmedetomidine is an alpha 2 adrenergic agonist, prolongs analgesia when used in neuraxial and peripheral nerve blocks. We studied the effect of addition of dexmedetomidine to bupivacaine to perform transversus abdominis plane (TAP) block. MATERIALS AND METHODS A total of 50 patients scheduled for abdominal hysterectomy were divided into two(More)
BACKGROUND Bispectral index (BIS) was developed to monitor patients' level of consciousness under general anesthesia. Several factors have been found to alter BIS readings without affecting the depth of anesthesia. We conducted a study to assess the impact of changing patients' position on BIS readings. METHODS General anesthesia was administered to 40(More)
OBJECTIVES Peribulbar anesthesia is associated with delayed and/or incomplete orbital akinesia compared with retrobulbar anesthesia. This study examined the effects of adding rocuronium 5 mg to two different concentrations of lidocaine-bupivacaine mixture on onset time of orbital and eyelid akinesia in patients undergoing cataract surgery. METHODS In a(More)
OBJECTIVE To assess the efficacy of pressure volume loop (PV-L) closure as an indicator of adequate endotracheal tube cuff (ETTc) function, and to compare this with commonly used methods of checking cuff pressure. METHODS We conducted a randomized clinical trial at the Department of Anesthesia, King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi(More)
The Bonfils retromolar intubation fiberscope is a rigid endoscope designed to enable glottic visualization and facilitate intubation under endoscopic vision. Theoretically, avoiding direct-vision laryngoscopy and thus could produce less stimulation during intubation than the conventional direct laryngoscopic procedure. This prospective randomized study was(More)
BACKGROUND The main function of an endotracheal tube (ETT) cuff is to prevent aspiration. High cuff pressure is usually associated with postoperative complications. We tried to compare cuff inflation guided by pressure volume loop closure (PV-L) with those by just to seal technique (JS) and assess the postoperative incidence of sore throat, cough and(More)
OBJECTIVE To determine the effect of modifying the GlideScope (GVL) blade on the intubation time. METHODS This prospective study was conducted at the Department of Anesthesia, King Abdulaziz University Hospital, Jeddah, Saudi Arabia between June 2011 and October 2011. Sixty patients requiring endotracheal tube (ETT) intubation for elective surgery in whom(More)
Providing sedation for patients with compromised upper airway is challenging. A 19-year-old female patient with huge maxillofacial tumor invading the whole pharynx scheduled for elective tracheostomy under local anesthesia due to compromised airway. The patient had gastrostomy tube for feeding. Venous cannulation was totally refused by the patient after(More)
