Summary
Nausea and vomiting are common during cesarean section anesthesia. Managing hypotension, opioids, and surgical stimuli can prevent these events, reserving antiemetics for high-risk patients.
Area of Science:
- Obstetric Anesthesia
- Surgical Complications
Background:
- Nausea and vomiting (N&V) are frequent and distressing during cesarean sections under regional anesthesia.
- Multiple factors contribute to N&V, including hypotension, vagal hyperactivity, visceral pain, opioids, uterotonics, and patient motion.
Purpose of the Study:
- To review anesthetic and non-anesthetic causes of intraoperative nausea and vomiting (IONV) during cesarean section.
- To outline prophylactic and therapeutic management strategies for IONV.
Main Methods:
- Literature review of anesthetic and non-anesthetic causes of IONV.
- Analysis of preventative and treatment strategies for IONV.
Main Results:
- IONV can be minimized by controlling hypotension, optimizing opioid use, enhancing block quality, reducing surgical stimuli, and judicious uterotonic administration.
- Prophylactic antiemetics are not always necessary if preventative measures are strictly followed.
Conclusions:
- Effective prevention of IONV during cesarean section relies on managing multiple causative factors.
- Antiemetics should be reserved for high-risk individuals or refractory cases of IONV.

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
01:29Local 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...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

01:24General 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...

01:22Stages 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...
01:24Parenteral 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.
