Combination Preemptive Peripheral Nerve Block in Limb Surgery. A Prospective Study.

: Patients often suffer from moderate to severe pain during the early recovery period in orthopedic surgery. We investigated the impact of a single-shot preoperative peripheral nerve block (PNB) on post-anesthesia recovery parameters and interleukin (IL)-6 level during limb surgery. A prospective randomized controlled study was conducted, and patients scheduled for limb surgery were recruited.

The Effectiveness of Low-dose Dexmedetomidine Infusion in Sedative Flexible Bronchoscopy: A Retrospective Analysis.

Flexible bronchoscopy has been widely used for diagnosis and intervention, while various drugs are used for sedation during bronchoscopy. We examined two regular standardized sedation options (with or without dexmedetomidine) regularly used in our regional hospital. The aim was to assess the efficacy and safety of dexmedetomidine on conscious sedation under bronchoscopy.

Propofol target-controlled infusion for sedated gastrointestinal endoscopy: A comparison of propofol alone versus propofol-fentanyl-midazolam.

Gastrointestinal (GI) endoscopy is the major technique for diagnosis of GI disease and treatment. Various sedation and analgesia regimens such as midazolam, fentanyl, and propofol can be used during GI endoscopy. The purpose of the study was to compare propofol alone and propofol combination with midazolam and fentanyl in moderate sedation for GI endoscopy.

Soft catheters reduce the risk of intravascular cannulation during epidural block--a retrospective analysis of 1,117 cases in a medical center.

A wet or bloody tap is an inevitable complication while performing epidural block. The influence of different catheters on the incidence of intravascular cannulation during epidural catheterization has not been reported. We observed an initial, relatively different incidence of intravascular cannulation during the placement of different sorts of epidural catheter; hence, a retrospective review was conducted to explore the possible association.

Pairagon: a highly accurate, HMM-based cDNA-to-genome aligner.

Motivation: The most accurate way to determine the intron-exon structures in a genome is to align spliced cDNA sequences to the genome. Thus, cDNA-to-genome alignment programs are a key component of most annotation pipelines. The scoring system used to choose the best alignment is a primary determinant of alignment accuracy, while heuristics that prevent consideration of certain alignments are a primary determinant of runtime and memory usage.

Clinical experience of pain treatment for postherpetic neuralgia in elderly patients.

Background: Postherpetic neuralgia (PHN) is a neuropathic pain syndrome that occurs following acute herpes zoster infection. The main clinical problem is intractable pain which interferes with activity of daily life and reduces the quality of life in the elderly patients. This retrospective study was to evaluate the outcome of pain treatment for the elderly patients with PHN at the Pain Clinic of Kaohsiung Medical University Hospital.

Ultrasound examination for the optimal head position for interscalene brachial plexus block.

Background: Surface anatomic landmarks have traditionally been used to locate the brachial plexus in the interscalene groove. Head rotation can affect the orientation of neck vessels and may possibly affect the brachial plexus. The optimal degree of head rotation has been specified for better internal jugular vein cannulation but not for interscalene brachial plexus block.

The feasibility of surface landmark for coracoid infraclavicular brachial plexus block by ultrasonographic assessment.

Background: The coracoid infraclavicular block first introduced by Whiffler provides a safer and easily approach than classic infraclavicular block. In this technique, the anatomy-based puncture site is 2 cm medial and 2 cm caudal from the coracoid process. This prospective study was purposed to evaluate the feasibility of surface landmark-based coracoid block by ultrasonography.

Seizure after local anesthesia for nasopharyngeal angiofibroma.

We report a young male patient who experienced seizure after local injection of 3 mL 2% lidocaine with epinephrine 1:200,000 around a recurrent nasal angiofibroma. After receiving 100% oxygen via mask and thiamylal sodium, the patient had no residual neurologic sequelae. Seizure immediately following the injection of local anesthetics in the nasal cavity is probably due to injection into venous or arterial circulation with retrograde flow to the brain circulation.
