A Proposed Methodology to Control Body Temperature in Patients at Risk of Hypothermia by means of Active Rewarming Systems

2014

Hypothermia is a common complication in patients undergoing surgery under general anesthesia. It has been noted that, during the first hour of surgery, the patient’s internal temperature (Tcore) decreases by 0.5–1.5°C due to the vasodilatory effect of anesthetic gases, which affect the body’s thermoregulatory system by inhibiting vasoconstriction. Thus a continuous check on patient temperature must be carried out. The currently most used methods to avoid hypothermia are based on passive systems (such as blankets reducing body heat loss) and on active ones (thermal blankets, electric or hot-water mattresses, forced hot air, warming lamps, etc.). Within a broader research upon the environment…

Publications on paediatric anaesthesia: a quantitative analysis of publication activity and international recognition.

2000

A comprehensive compilation of the current international literature on paediatric anaesthesia is lacking. The aim of this study was to identify all articles on clinical practice in paediatric anaesthesia, to name the respective journals, and to assess the publication activity and international recognition of selected countries for a 6-yr period (1993–1998). The search comprised an article-to-article evaluation (‘hand search') of 12 peer-reviewed anaesthesia journals, as well as an Internet-based (‘SilverPlatter') MedlineTM-search (3.900 medical journals, US National Library of Medicine), both limited to original articles, case reports, reviews and editorials. Selected physical characteristi…

Laser Therapy for Infected Sites and Immediate Dental Implants in the Esthetic Zone: A Case Report and Review of Literature

2020

Placement of postextraction dental implants has become a common practice. Here, we reviewed current literature, along with clinical procedures, outcomes, and incidence of complications, associated with immediate implants in infected postextraction sites. The YSGG (yttrium, scandium, gallium, and garnet) laser can significantly reduce the bacterial concentration after extracting a compromised tooth. We treated a 40-year-old woman with a compromised tooth in the esthetic zone, presenting clinical and radiological signs of infection, particularly a periapical periodontitis. The tooth was extracted after administering local anesthesia using Optocain® (mepivacaine and adrenalin 1 : 100,000), fol…

Pressure Monitoring of Intraneural an Perineural Injections Into the Median, Radial, and Ulnar Nerves; Lessons From a Cadaveric Study

2015

Background: Nerve damage after regional anesthesia has been of great concern to anesthetists. Various modalities have been suggested to recognize and prevent its incidence. An understudied area is the measurement of intraneural pressure during peripheral nerve blockade. Previous investigations have produced contradicting results with only one study being conducted on human cadavers. Objectives: The purpose of this investigation was to systematically record intraneural and perineural injection pressures on the median, ulnar, and radial nerves exclusively as a primary outcome. Materials and Methods: Ultrasonography-guided injections of 1 mL of 0.9% NaCl over ten seconds were performed on phen…

Eine Methode zur Beurteilung des Nierengef��tonus bei M�usen

1955

Durch den Vergleich von in vivo unterbundenen und nichtunter-bundenen Nieren last sich mit Hilfe der Benzidinfarbung von Slonimski u. Cunge der Tonuszustand von Nierengefasen feststellen. Im Excitations-und Toleranzstadium der Athernarkose findet eine Tonuserhohung der Rindengefase statt, im Asphyxiestadium eine allgemeine renale Gefasdilatation. Methodik und Ergebnisse werden mit den Befunden von Still u. Whitcomb vor allem in bezug auf einen Trueta-Shunt diskutiert.

Simple and convenient remote photoplethysmography system for monitoring regional anesthesia effectiveness

2017

Simple and inexpensive remote photoplethysmography system for monitoring the effectiveness of regional anesthesia was developed and tested. The system involves surgical lamp as light source, compact video camera and computer with custom developed software. Data from eight patients were processed and the effectiveness of regional anesthesia was calculated. The results showed that the standard surgical lamp can be used as a light source together with camera for remote monitoring of regional anesthesia effectiveness.

Comparison of two needle models in terms of bevel deformation during truncal block of the inferior alveolar nerve

2007

Objectives: To evaluate the differences in terms of bevel deformation between two types of needle of the same length and external caliber, but with different internal diameters, during truncal block of the inferior alveolar nerve. Study design: Four operators performed truncal block of the inferior alveolar nerve and infiltrating anesthesia of the buccal nerve for the extraction of a lower third molar in 266 patients. The truncal block was carried out using a standard 27G x 35 mm needle with an internal caliber of 0.215 mm, or a 27G x 35 mm XL Monoprotect® needle with an internal caliber of 0.265 mm. The infiltrating anesthesia was made with a Monoprotect® or XL Monoprotect® needle, both wi…

A comparison of injection pain with articaine with adrenaline, prilocaine with phenylpressin and lidocaine with adrenaline

2008

Kutuk, Nukhet/0000-0001-6563-1899 WOS: 000259667200006 PubMed: 18587306 Objective: The objective of the present study was to investigate the pain on injection of articaine with adrenaline, prilocaine with phenylpressin, and lidocaine with adrenaline. Study Design: The study sample was comprised of 497 consecutively seen patients received 497 maxillary buccal infiltration injections or inferior alveolar block injections of 4% articaine with 1: 200.000 adrenaline, 3% prilocaine with 1.08mcg phenylpressin, or 2% lidocaine with 1: 100.000 adrenaline. Immediately after the injection, patients were asked to rate their injection pain on a six-point scale. Results: There were no significant differe…

Intravenous Regional Anesthesia

1988

Intravenous regional anesthesia was first described by Bier in 1908. The technique fell into disuse until 1963, when Holmes revived the technique by substituting lidocaine for procaine (see Sect. V. D, “Choice and Dosage of Agents”).
