BACKGROUND Digital nerve block is commonly performed by care providers in medical fields. This study compares the blocks in terms of effectiveness of anesthesia and pain. METHODS Patients were divided into two groups. First group underwent digital block whereas 2nd group had transmetacarpal digital block. The subcutaneous ring block was performed by two injections of 3 ml of 2% lignoca...

The aim of this study was to investigate the anesthetic effect and risk of epinephrine for subcutaneous single injection digital block. Either 3.0 mL 1.0% Lidocaine or a 3.0 mL 1.0% Lidocaine with (1 : 100,000) epinephrine was injected into the subcutaneous space at the middle point of the palmar digital crease of the 18 middle fingers of 9 healthy volunteers. The SpO(2) of the fingers decrease...

Pulse oximetry is dependent upon the presence of a pulsating vascular bed. Low pulsatile blood flow in the digits is caused by various factors. Regardless of the cause, if there is sufficient arterial pulse pressure, blocking the sympathetic nerve should cause a local increase in capillary flow and pulse volume. This study was performed to evaluate the effect of digital nerve block on pulse oxi...

Digital neural loops were identified over a century ago and are common findings in cadaveric studies of palmar and digital anatomy. Symptomatic digital neural loops are rare. We report a case of hemidigital anesthesia resulting from a proper digital nerve neural loop penetrated by its common digital artery in the palm. After neurolysis of the median nerve and the common and proper digital nerve...

Recent healthcare legislation, financial pressures, and regulatory oversight have increased the need to create improved mechanisms for performance measurement, quality management tracking, and outcomesbased research. The Anesthesia Quality Institute (AQI) has established the National Anesthesia Clinical Outcomes Registry (NACOR) to support these requirements for a wide-range of customers includ...

Traditionally, surgeons were taught that local anesthesia containing epinephrine should not be injected into fingers. This idea has since been refuted in many basic and clinical scientific studies, and today, injection of lidocaine plus epinephrine is widely used for digital and hand anesthesia in Canada. The key advantages of the wide-awake technique include the creation of a bloodless field w...

The Proseal laryngeal mask airway (PLMA) (The Laryngeal Mask Company Ltd., Victoria, Seychelles) is an advanced form of the LMA with a softer and larger cuff to improve sealing and a drain tube to permit venting of the stomach. However, when a larger cuff is used, it is more difficult to save space for inserting the PLMA in the patient's mouth, and the larger cuff is more likely to fold over (1...
