Effects of vasoconstrictor use on digital nerve block: systematic review with meta-analysis.

Rev Col Bras Cir 2020 20;46(6):e20192269. Epub 2020 Jan 20.

Centro Universitário Tiradentes, Curso de Medicina, Maceió, AL, Brasil.

Conventionally, the association of local anesthetics with vasoconstrictors is avoided at extremities due to the risk of ischemia. However, recent studies suggest that there is safety in the use of vasoconstrictors at extremities. Thus, we sought to evaluate the effectiveness and safety of vasoconstrictor use combined with local anesthetics in digital nerve block compared to the use of anesthetics without vasoconstrictors, through a systematic review with meta-analysis of randomized clinical trials.

Morphological analysis of mandibular foramen through anatomical planes: implications for inferior alveolar nerve block.

Anat Sci Int 2020 Mar 15;95(2):209-218. Epub 2019 Nov 15.

Department of Anatomy, 3rd Floor, All India Institute of Medical Sciences, Phulwarisharif, Patna, Bihar, 801507, India.

Error in localization of mandibular foramen is attributed to a high failure rate of inferior alveolar nerve block in clinical dentistry. We hypothesized that a remodelled approach towards exploring the morphology of mandibular foramen would be useful. In the present study, the location of the mandibular foramen was analysed with respect to the anatomical planes across the ramus of the mandible and also with respect to the quadrants on the medial surface of ramus of mandible.

Is Epinephrine Safe for Infant Digit Excision? A Retrospective Review of 402 Polydactyly Excisions in Patients Younger than 6 Months.

Plast Reconstr Surg 2019 07;144(1):149-154

From the Division of Plastic Surgery, Children's National Health System.

Background: Conventional dogma suggests that the use of local anesthetic with epinephrine is contraindicated in the digits because of fear of ischemia and necrosis. Although several reports have refuted this notion, the precept is still propagated in many clinical forums. For many years, the authors have used lidocaine with epinephrine to perform removal of postaxial polydactyly in infants and have observed few complications and no cases of digital ischemia or necrosis.

Changes in facial temperature measured by digital infrared thermal imaging in patients after transnasal sphenopalatine ganglion block: Retrospective observational study.

Medicine (Baltimore) 2019 Apr;98(15):e15084

Department of Anesthesiology and Pain Medicine, Ajou University, School of Medicine, Suwon, South Korea.

Sphenopalatine ganglion block (SPGB) is a technique developed in the 1990s for the management of head and neck pain patients. Recently, transnasal sphenopalatine ganglion block (TN-SPGB) has been widely used for these patients; however, no objective methods exist for validating the success of TN-SPGB. In this study, we measured the changes in facial temperature before and 30 minutes after TN-SPGB by using digital infrared thermal imaging (DITI) to validate its success. Read More

Evaluation of the B-Smart manometer and the CompuFlo computerized injection pump technology for accurate needle-tip injection pressure measurement during peripheral nerve blockade.

Reg Anesth Pain Med 2019 01;44(1):86-90

Department of Anesthesiology, University of Miami - Miller School of Medicine, Miami, Florida, USA.

Background And Objectives: The exact mechanism of peripheral nerve blocks causing/leading to nerve injury remains controversial. Evidence from animal experiments suggests that intrafascicular injection resulting in high injection pressure has the potential to rupture nerve fascicles and may consequently cause permanent nerve injury and neurological deficits. The B-Smart (BS) in-line manometer and the CompuFlo (CF) computerized injection pump technology are two modalities used for monitoring pressure during regional anesthesia. Read More

Comparison of the Cost and Efficacy of Axillary Anesthesia and Wide-Awake Anesthesia in Finger Surgeries.

Sisli Etfal Hastan Tip Bul 2018 12;52(2):119-123. Epub 2018 Jun 12.

Department of Orthopedics, University of Health Sciences, Erzurum Regional Training and Research Hospital, Erzurum, Turkey.

Objectives: Wide-awake anesthesia is a type of local anesthesia consisting of a combined application of lidocaine, epinephrine, and bicarbonate and has a wide potential in hand surgery as it offers the advantage of being applied without sedation and without using a tourniquet. In light of recent studies, its use has increased with the disappearance of the belief among surgeons that epinephrine can cause circulatory disturbance in fingers.

Methods: Patients with finger pathologies who were operated upon at the Baltalimani Bone Diseases Teaching and Research Hospital between January 2015 and February 2016 were divided into two groups according to anesthesia type: wide-awake anesthesia and axillary block anesthesia, with 52 patients in each group.
