Detailed Description

Fractures of the forearm are extremely common, Pain relief is of utmost importance in forearm fractures which may need manipulation immediately for reduction followed by operative intervention

The characteristic features of ideal analgesia during reduction are determined by safety, simplicity, affectivity and costs. Giventhe logistic difficulty of providing such anesthesia to such large number of patients simpler alternatives to conventional anesthesia have been tried. Hematoma Block alone, Hematoma Block with sedation, Bier's Block (Intravenous regional anesthesia), regional nerve blocks, sedation have been compared to general anesthesia to evaluate the efficacy, effectiveness, safety in treating such patients

Amongst various techniques, HB and IVRA are attractive options. However, while HB has been demonstrated to be safe simple and has been used effectively for treatment of radius fractures in ER and for immediate pain relief it doesn't provide muscular relaxation and may not be sufficient for any operative intervention

IVRA is suitable for operations of the distal extremities, in situations where it is safe and easy to apply an occlusive tourniquet. The primary advantages of IVRA are its simplicity, reliability, and cost-effectiveness. . It is a regional anesthetic technique that is easy to perform, with success rates varying between 94% and 98%.For these reasons, it remains a popular choice among anesthesiologists.

A combination of blocks is usually done to overcome the deficiencies of individual blocks and to improve operating conditions or to prolong post operative analgesia. However the use of dual technique of IVRA and HB with local anesthetic only offered near absence of post operative analgesia

Lidocaine is the most frequently used LA for IVRA and HB

Different agents have been used as additive to local anesthetic for IVRA including phencyclidines, non-steroidal anti inflammatory drugs, opioids, and muscle relaxants. Ketamine is an effective anesthetic agent for IVRA at concentrations between 0.3% and 0.5%.it improves quality of anesthesia and peri operative analgesia without causing side effects

Ketamine, a phenyl-piper dine derivative, was first synthesized in the early 1960 as an IV anesthetic agent. At sub anesthetic doses, ketamine exerts a noncompetitive blockade of N -methyl aspartate (NMDA) receptors. NMDA receptors play a major role in synaptic plasticity and are specifically implicated in central nervous system facilitation of pain processing. NMDA receptor antagonists have been implicated in perioperative pain management. Ketamine also has local anesthetic qualities, which have been studied as a sole agent for IVRA. In addition to spinal cord NMDA receptors, NMDA receptors have also been identified on peripheral unmyelinated sensory axons. This can explain why ketamine as an NMDA receptor antagonist was able to attenuate the tourniquet pain.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
