Objective: To investigate the feasibility of a non-stimulation needle with an external indwelling cannula for upper-limb surgery and acute postoperative pain management. Methods: 62 patients undergoing either scheduled or emergency upper-limb surgery received brachial plexus block of modified interscalene or axillary brachial and then postoperative patient-controlled analgesia (PCA) with local analgesics using a specially designed non-stimulation needle with an external indwelling cannula. The outcome measurements included anesthetic effect, acute or chronic complications, postoperative analgesic effect and patient’s satisfaction. Results: The success rate of anesthesia was 96.8%. The single attempt placement with the external indwelling cannula was achieved in 85.2% of patients with axillary brachial plexus block and 78.8% with modified interscalene brachial plexus block. The incidence of severe intoxication was 3.7% with axillary brachial plexus block and 3.0% with modified interscalene brachial plexus block. No hematoma at the injection site, Horner’s syndrome, hoarseness or dyspnea was observed. Postoperative analgesic effect was achieved in 100% and activities were slightly lowered in 91.7%. The incidence of nausea and vomit was 8.3%; patient’s satisfaction was 9.1 on a 10-point scale system. Infection, nerve injury and respiratory depression were absent during the catheter indwelling. The indwelling time of external indwelling cannula was 30.5 h on average. There was no nerve injury related complication after withdrawing the external indwelling catheter. Conclusions: Brachial plexus block using a non-stimulation needle with an external indwelling cannula has favorable intra-operative anesthetic benefit and provides an excellent postoperative analgesic outcome. The low incidence of complications and favorable patient’s satisfaction suggest that non-stimulation needle with an external indwelling cannula is a useful and safe anesthetic tool in brachial nerve block and acute postoperative pain management.

The aim of this study is to evaluate the clinical, electroencephalographic and polysomnographic features of patients presenting with parasomnias. Cases who were admitted for differentiating parasomnias from epilepsy were included in the study. Clinical features of cases were recorded and routine sleep electroencephalography was obtained from all cases. Cases whose symptoms strongly suggested nocturnal seizure underwent all night video electroencephalography monitoring. Polysomnography was obtained to evaluate the quality of breathing from patients whose symptoms suggested obstructive sleep apnea. Twenty-three patients with no neurological disorder were included in the study. The mean age of the patients was 11.7 ± 2.8 [7-17] years. Twelve patients (52 %) presented with sleep terrors and 11 patients (48 %) presented with sleep walking. All of the patients underwent a routine sleep electroencephalographic study and 15 patients (65 %) whose symptoms strongly suggested nocturnal epilepsy underwent long-term video electroencephalographic evaluation. Ten patients (43 %) underwent polysomnographic study. Three patients (20 %) who underwent long-term video electroencephalographic evaluation were diagnosed to have nocturnal frontal lobe epilepsy and two patients (20 %) who underwent polysomnography had pathological sleep apnea. Eleven patients (48 %) had a psychiatric disorder like major depression, anxiety disorder, hyperactivity disorder and obsessive-compulsive disorder. Childhood cases presenting with parasomnias should be searched for nocturnal epileptic disorders, sleep disordered breathing and psychiatric disorders.

Background:Microcannulas with blunt tips for filler injections have recently been developed for use with dermal fillers. Their utility, ease of use, cosmetic outcomes, perceived pain, and satisfaction ratings amongst patients in terms of comfort and aesthetic outcomes when compared to sharp hypodermic needles has not previously been investigated. Objective: To compare injections of filler with microcannulas versus hypodermic needles in terms of ease of use, amount of filler required to achieve desired aesthetic outcome, perceived pain by patient, adverse events such as bleeding and bruising and to demonstrate the advantages of single-port injection technique with the blunt-tip microcannula. Materials and Methods:Ninety-five patients aged 30 to 76 years with a desire to augment facial, décolleté, and hand features were enrolled in the study. Subjects were recruited in a consecutive manner from patients interested in receiving dermal filler augmentation. Each site was cleaned with alcohol before injection. Anesthesia was obtained with a topical anesthesia peel off mask of lidocaine/tetracaine. Cross-linked hyaluronic acid (20 mg to 28 mg per mL) was injected into the mid-dermis. The microcannula or a hypodermic needle was inserted the entire length of the fold, depression or lip and the filler was injected in a linear retrograde fashion. The volume injected was variable, depending on the depth and the extent of the defect. The injecting physician assessed the ease of injection. Subjects used the Visual Analog Scale (0-10) for pain assessment. Clinical efficacy was assessed by the patients and the investigators immediately after injection, and at one and six months after injection using the Global Aesthetic Improvement Scale (GAIS) and digital photography. Results: Overall, the Global Aesthetic Improvements Scale (GAIS) results were excellent (55%), moderate (35%), and somewhat improved (10%) one month after the procedure, decreasing to 23%, 44%, and 33%, respectively, at the six month evaluation. There was no significant differences in the GAIS score between the microcannula and the hypodermic needle. However, the Visual Analog Scale for pain assessment during the injections was quite different. The pain was described as 3 (mild) for injections with the microcannula, increasing to 6 (moderate) for injections with the hypodermic needle. Bruising and ecchymosis was more marked following use of the hypodermic needle. Conclusion:Using the blunt-tip microcannula as an alternative to the hypodermic needles has simplified filler injections and produced less bruising, echymosis, and pain with faster recovery.
