General Anesthesia: Overview

General Anesthesia: Overview

Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Parenteral Anesthetics: Overview

Parenteral Anesthetics: Overview

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.

Skeletal Muscle Relaxants: Therapeutic Uses

Skeletal Muscle Relaxants: Therapeutic Uses

Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...

Stages of General Anesthesia

Stages of General Anesthesia

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Inhalational Anesthetics: Overview

Inhalational Anesthetics: Overview

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: Clinical Application as Epidural Anesthesia

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Area of Science:

Anesthesiology
Surgical Complications
Obesity Medicine

Background:

Parotid gland swelling is a rare complication associated with general anesthesia across various patient demographics and surgical procedures.
This condition, while uncommon, necessitates awareness among healthcare providers for accurate diagnosis and management.
The association between morbid obesity and this complication has not been widely reported.

Observation:

A 45-year-old morbidly obese female (BMI 50.5 kgm-2) developed unilateral painful parotid gland swelling postoperatively.
The swelling occurred on the dependent side after surgery for a left humerus fracture, managed with the patient in a right lateral position.
Head positioning during surgery utilized a soft bandage head ring, a standard practice for such procedures.

Findings:

The case suggests a potential link between morbid obesity and parotid gland swelling post-surgery.
A proposed mechanism involves the unique cervical anatomy of morbidly obese patients, leading to vascular compression and compromised blood flow.
This compromised perfusion may result in ischemic sialadenitis, manifesting as parotid gland swelling.

Implications:

Physicians should consider parotid gland swelling as a potential complication in morbidly obese patients, especially after procedures requiring specific positioning.
Recommendations include minimizing neck manipulation and ensuring adequate facial padding during surgery.
Discouraging the use of head rings for head positioning in morbidly obese patients may help prevent this complication.
