Anesthetize Lobster Ice

Anesthetizing a lobster with ice is a biological handling technique that uses cold temperatures to reduce movement before observation, dissection, or other procedures. Placing the lobster in an ice-cooled environment lowers body temperature, slowing metabolic activity and neuromuscular function; the animal should remain chilled only for the period supported by the experimental protocol. In biology laboratories, this approach can improve handling control and help standardize procedures involving lobster anatomy, physiology, or tissue collection. Because cold exposure may not eliminate sensory responses, researchers should follow species-appropriate welfare guidelines and verify that the method is suitable for the intended application.

2014

Fishery-induced changes to exploited crustacean fisheries, such as the American lobster fishery, could potentially influence their reproductive dynamics, leading to a reduction in mating success. This study's goal was to develop a noninvasive method for ascertaining the mating success of female lobsters that may be physiologically or functionally mature.

Inhalational Anesthetics: Overview

0 Views •

2024

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...

Local Anesthetics: Pharmacokinetics

2023

The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...

Parenteral Anesthetics: Overview

2024

Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
