Summary
Managing filler-related vascular occlusion (VO) is challenging. Adjunctive nitrous oxide (N2O) with hyaluronidase injections eased patient pain and anxiety, improving skin perfusion in two VO cases.
Area of Science:
- Dermatology
- Aesthetic Medicine
- Pain Management
Background:
- Filler-related vascular occlusion (VO) treatment is complex, often involving hyaluronidase injections and ultrasound guidance.
- Patient pain and anxiety during VO treatment are significant management challenges.
- Nitrous oxide (N2O) is established for analgesia and anxiolysis in other procedures.
Observation:
- Two cases of filler-related VO were treated with high-dose hourly hyaluronidase and self-administered 50% N2O.
- Patients self-reported pain and anxiety levels.
- Skin perfusion was monitored via capillary refill and livedo reticularis to assess VO treatment outcomes.
Findings:
- Self-administered N2O provided immediate improvement in skin perfusion.
- Patients reported significant reductions in pain and anxiety during the procedure.
- Hyaluronidase treatment successfully resolved VO symptoms permanently.
Implications:
- Nitrous oxide (N2O) shows promise as an adjunctive therapy for managing pain and anxiety in filler-related VO.
- N2O may offer additional benefits in improving skin perfusion during VO treatment.
- Further research is needed to establish the role and optimal use of N2O in VO management.

Nitric Oxide Signaling Pathway
5.1K
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

Drug Delivery: Enteral Route
510
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Antianginal Drugs: Nitrates and β-Blockers

In cardiovascular health, antianginal drugs combat angina pectoris — a condition marked by chest pain owing to diminished blood flow to the heart.
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....

Antihypertensive Drugs: Vasodilators
568
Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...

Inhalational Anesthetics: Overview
339
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

Autoregulation of Blood Flow
2.4K
Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
