Abstract

Insights

Methamphetamine-positive burn patients face higher graft loss rates, increasing the need for re-grafting. Early identification through toxicology screening is crucial for intensive burn management and improved outcomes.

Area of Science:

  • Burn surgery
  • Trauma surgery
  • Toxicology

Background:

  • Methamphetamine intoxication is linked to severe medical complications in burn patients, including extended intensive care unit (ICU) stays and increased sepsis rates.
  • The impact of methamphetamine use on the durability and success of skin grafts in burn patients remains largely unknown.
  • This study investigates the association between methamphetamine use and graft loss in adult burn patients.

Purpose of the Study:

  • To determine if methamphetamine-positive burn patients experience higher rates of autograft loss compared to methamphetamine-negative patients.
  • To identify potential risk factors and clinical outcomes associated with methamphetamine use in burn care.
  • To inform clinical practice regarding the management of burn patients with a history of methamphetamine use.

Main Methods:

  • A retrospective cohort study was conducted at a verified burn center, including adult patients admitted between 2021 and 2024.
  • Patients aged 18 years and older with toxicology screening for methamphetamine were included; those without screening were excluded.
  • The primary outcome was graft loss requiring re-operation, with data on demographics, burn etiology, graft type, ICU days, and length of stay collected.

Main Results:

  • Out of 746 patients, 112 were methamphetamine-positive. Methamphetamine users showed significantly higher rates of autograft loss (p < 0.001).
  • Methamphetamine-positive patients had larger total burn surface areas (TBSA) (p = 0.01), longer hospital stays (p = 0.03), and increased likelihood of intubation (p = 0.01).
  • Flame burns were the primary etiology in methamphetamine users (p < 0.001), contrasting with scald burns in non-users (p < 0.001).

Conclusions:

  • Methamphetamine use is a significant risk factor for graft loss in burn patients, necessitating specialized management.
  • Patients testing positive for methamphetamine were more prone to flame burns and autograft failure.
  • Routine toxicology screening can aid in early identification, allowing for proactive and intensive burn management strategies.

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
Phase II Reactions: Methylation Reactions01:17

Phase II Reactions: Methylation Reactions

Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...

Drug Abuse and Addiction: Pharmacological Phenomena

Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...

Drug Toxicity: Dose-Dependent Reactions

Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
Stimulants01:29

Stimulants

Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...
