Lower incidence of hypotension following spinal anesthesia with 6% hydroxyethyl starch preload compared to 9 ‰ saline solution in caesarean delivery.

Background: Hypotension is a common complication following spinal anesthesia for cesarean delivery. Techniques to prevent hypotension include preloading intravenous fluid.

Aim: To compare the effect of two preloading regimens: 6% hydroxyethyl starch (HES) and 9‰ saline solution, to prevent hypotension after spinal anesthesia in cesarean delivery.

Effect of Ondansetron on the Occurrence of Hypotension and on Neonatal Parameters during Spinal Anesthesia for Elective Caesarean Section: A Prospective, Randomized, Controlled, Double-Blind Study.

To prevent hypotension during spinal anesthesia for caesarean section, we assessed IV ondansetron of invasive maternal hemodynamic and fetal gazometric parameters.

Ultrasound-guided spinal anesthesia in an obese patient.

We describe the case of 62-year-old man with a body mass index of 53, hypertension, diabetes mellitus and obstructive sleep apnea that was proposed for transurethral resection of prostate under spinal anesthesia. The surface landmark-guided approach was difficult and was abandoned after many unsuccessful attempts. Spinal anesthesia was achieved in one attempt with ultrasound guidance using the midline approach at the identified level.

Ultrasound does not shorten the duration of procedure but provides a faster sensory and motor block onset in comparison to nerve stimulator in infraclavicular brachial plexus block.

Background: Infraclaviculr Brachial plexus (ICBP) block is useful for upper extremity surgery. The aim of this study was to compare the ultrasound (US) technique with the nerve stimulation (NS) technique in their success rates and times to perform ICBP block.

Methods: 60 patients undergoing surgery of the upper limb were randomly allocated into two groups (n = 30 per group).

A Case of Horner's Syndrome following Ultrasound-Guided Infraclavicular Brachial Plexus Block.

Horner's syndrome results from paralysis of the ipsilateral sympathetic cervical chain (stellate ganglion) caused by surgery, drugs (mainly high concentrations of local anesthetics), local compression (hematoma or tumor), or inadequate perioperative positioning of the patient. It occurs in 100% of the patients with an interscalene block of the brachial plexus and can also occur in patients with other types of supraclavicular blocks.In this case report, we presented a case of Horner's syndrome after performing an ultrasound-guided infraclavicular brachial plexus block with 15 mL of bupivacaine 0.

[Effects of 15 mcg intrathecal clonidine added to bupivacaine and sufentanil for labor analgesia].

Background: For the combined spinal epidural analgesia for labour, 30 mcg of subarachnoid clonidine has proved its effectiveness to extend the analgesia, but increased severe hemodynamic effects.

Aim: To assess the effectiveness and the safety of 15 mcg intra thecal clonidine for labour analgesia.

Methods: Four months, prospective, randomised, simple blind Study, including ASA I or II women, with mono foetal pregnancy.

Cardiac surgery in patients on hemodialysis: eight years experience of the Tunisian military hospital.

End-stage renal disease (ESRD) is known to be an important risk factor for cardiac operations performed with cardiopulmonary bypass. We investigated the influence of preoperative status on perioperative mortality and morbidity. We retrospectively analyzed data from 26 patients with ESRD, who were on maintenance dialysis and underwent a cardiac surgical procedure bet-ween 2000 and 2007.
