Background: We prospectively tested technical feasibility and clinical outcome of percutaneous ultrasound-guided tenotomy of long head of biceps tendon (LHBT). Methods: We included 11 patients (6 women; age: 73 ± 8.6 years) with symptomatic full-thickness rotator cuff tear and intact LHBT, in whom surgical repair was not possible/refused. After ultrasound-guided injection of local anesthetic, the LHBT was cut with a scalpel under continuous ultrasound monitoring until it became no longer visible. Pain was recorded before and at least six months after procedure. An eight-item questionnaire was administered to patients at follow-up. Results: A median of 4 tendon cuts were needed to ensure com…

Local anaesthetic sympathetic blockade for complex regional pain syndrome

2016

This is the peer reviewed version of the following article: The Cochrane database of systematic reviews, which has been published in final form at https://doi.org/10.1002/14651858.CD004598.pub4. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving. Background: This review is an update of a previously published review in the Cochrane Database of Systematic Reviews, 2005, Issue 4 (and last updated in the Cochrane Database of Systematic Reviews, 2013 issue 8), on local anaesthetic blockade (LASB) of the sympathetic chain to treat people with complex regional pain syndrome (CRPS). Objectives: To assess the efficacy of LASB for the…

Comparison of success rate and onset time of two different anesthesia techniques

2014

Background: Using local anesthetic is common to control the pain through blocking the nerve reversibly in dental procedures. Gow-Gates (GG) technique has a high success rate but less common. This study aimed to compare the onset time and success rate in GG and standard technique of inferior alveolar nerve block (IANB). Material and Methods: This descriptive, single blind study was consisted of 136 patients (59 males and 77 females) who were randomly received GG or IANB for extraction of mandibular molar teeth. Comparisons between the successes of two anesthetic injection techniques were analyzed with Chi-square test. Incidence of pulpal anesthesia and soft tissue anesthesia were analyzed wi…

Evaluation of the plasmatic level of mepivacaine in different anatomical regions

2018

Background To evaluate the serum level of the local anesthetic mepivacaine 3% without vasoconstrictor in patients who underwent procedures performed in the anterior and posterior maxilla, through a method of possible extraction to quantify it in human plasma by high performance liquid chromatography (HPLC). Material and Methods This was a hybrid study consisting of 18 patients (7 females and 11 males) classified as ASA I, adults and with normal body mass index, submitted to procedures in the anterior region (group I) and posterior region of the maxilla (group II). For 40 minutes, five 6 ml blood samples were collected every 10 minutes after infiltrative injection in each region of the maxil…

Ophthalmologic complications after intraoral local anesthesia with articaine.

2000

A series of 14 cases of ophthalmologic complications after intraoral anesthesia of the posterior superior alveolar nerve is presented. The most commonly encountered symptoms were diplopia, mydriasis, palpebral ptosis, and abduction difficulties of the affected eye. In all cases, these effects occurred a few minutes after injection of the anesthetic, followed by complete resolution without sequelae on cessation of the anesthetic effect. The pathogenic mechanism underlying such ophthalmologic disorders is discussed in terms of a possible diffusion of the anesthetic solution toward the orbital region.

Local anesthetic switching for intrathecal tachyphylaxis in cancer patients with pain.

2003

IMPLICATIONS Switching from bupivacaine to lidocaine may improve intrathecal morphine analgesia in advanced cancer patients, possibly because of different spinal mechanisms limiting the hyperalgesic processes.

Alternative treatments of breakthrough pain in patients receiving spinal analgesics for cancer pain.

2005

Patients who experience a poor response to different systemic opioid trials (oral and intravenous) are candidates for spinal treatment. Breakthrough pain occurring in this group of patients is challenging for physicians. This phenomenon has never been described in this context and the treatment is quite difficult, as patients already demonstrated a poor response to systemic opioids. We report a preliminary experience of alternative methods, including the intrathecal injection of local anesthetic boluses as needed, or alternatively, the use of sublingual ketamine. Twelve consecutive patients with advanced cancer and pain were selected for intrathecal treatment after receiving different trial…

Hemodynamic and ventilatory changes during implant surgery with intravenous conscious sedation

2010

Purpose: This study was conducted to determine the hemodynamic and ventilatory changes during implant surgery with intravenous conscious sedation, and whether preoperative anxiety, gender or age influence these parameters. Patients and Methods: A prospective study carried out between May 2004 and February 2007, on 102 patients treated with dental implants under local anesthesia and conscious intravenous sedation. Patients completed a questionnaire prior to surgery to evaluate preoperative dental anxiety using Corah's scale. The hemodynamic and ventilatory changes were evaluated by monitoring systolic pressure (SP), diastolic pressure (DP), heart rate (HR) and oxygen saturation (SaO2). These…

Cocaine or phenylephrine/lignocaine for nasal fibreoptic intubation?

1996

In order to assess if a mixture of phenylephrine/lignocaine is as effective as cocaine for local analgesia and vasoconstriction during nasal fibreoptic intubation, 99 patients receiving topical nasal analgesia either with cocaine 10% or a mixture of phenylephrine 1% and lignocaine 4% were studied in a randomized double-blind investigation. After topical analgesia a flexible fibreoptic endoscope was advanced through a nostril. Larynx, glottis and trachea were endoscopically sprayed with lignocaine. Following induction of anaesthesia a nasotracheal tube was inserted fibreoptically. Pain intensity and amount of epistaxis during endoscopy were assessed. Blood pressure, heart rate and ECG-ST seg…

Prenatal cocaine exposure alters spontaneous and cocaine-induced motor and social behaviors.

2005

The abuse of cocaine in pregnant women could affect emotional behaviors in their descendents. The aim of this work was to evaluate the effects of prenatal cocaine exposure on spontaneous and cocaine-induced motor and social behaviors in mice. Three kinds of prenatal treatment were used: non-treated animals; mice treated daily with physiological saline during the last week of pregnancy; and finally, those treated with cocaine (25 mg/kg) during the same period. Behavioral studies took place on adult males, which were housed in two different conditions: grouped (non-aggressive), or isolated (aggressive). Cocaine-pretreated animals exhibited slight differences in spontaneous motor activity, but…
