Summary
Chlorhexidine gluconate (CHG) skin antisepsis before spinal anesthesia did not increase neurologic complication rates. This study supports CHG use for lumbar puncture, showing safety comparable to existing methods.
Area of Science:
- Anesthesiology
- Infectious Disease Prevention
- Neurosurgery
Background:
- Neuraxial procedures require strict aseptic technique to prevent infectious complications.
- Chlorhexidine gluconate (CHG) offers advantages over other antiseptics but lacks FDA approval for lumbar puncture due to limited clinical safety data.
- This study addresses the safety of CHG for spinal anesthesia antisepsis.
Purpose of the Study:
- To evaluate if chlorhexidine gluconate (CHG) skin antisepsis before spinal anesthesia is associated with a different incidence of neurologic complications compared to historical data.
- To test the hypothesis that CHG use does not increase the risk of neurologic complications after spinal anesthesia.
Main Methods:
- A retrospective cohort study analyzed patients aged 18+ undergoing spinal anesthesia between 2006-2010.
- The primary outcome was new or progressive neurologic deficit within 7 days of anesthesia.
- Neurologic complication etiology was independently assessed by three investigators, requiring consensus for classification.
Main Results:
- 11,095 patients received 12,465 spinal anesthetics; 57 cases (0.46%) had neurologic complications.
- Spinal anesthesia was implicated in 5 cases (0.04%), all resolving within 30 days.
- The incidence of neurologic complications was consistent with previous reports.
Conclusions:
- The incidence of neurologic complications possibly linked to spinal anesthesia after CHG antisepsis (0.04%) aligns with existing literature.
- Findings support the use of CHG for skin antisepsis prior to spinal anesthesia, indicating no increased risk of anesthetic-related neurologic complications.

01:12Local Anesthetics: Adverse Effects
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

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...

01:24General 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...

01:19Depolarizing Blockers: Pharmocokinetics
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...
01:21Skeletal Muscle Relaxants: Adverse Effects
Skeletal muscle relaxants are widely used for muscle paralysis and relieving pain following any muscle injury or stiffness. However, depending on the drug type, they can have adverse effects that range from mild to severe. Usually, nondepolarizing neuromuscular blockers have minimal side effects. For example, drugs like d-tubocurarine, cisatracurium, and rocuronium cause hypotension, whereas drugs like baclofen, when stopped abruptly, can lead to the recurrence of spastic conditions.
