Study Notes
Antibiotics in Tonsillectomy
- The administration of antibiotics for prevention or control of infection should be preceded by a comprehensive analysis of the potential benefits and risks.
- Perioperative use of antibiotics is justified only in selected cases, i.e., in individuals with comorbidities.
Nerve Injuries Following Neck Dissections
- The estimated prevalence of the shoulder syndrome/spinal accessory nerve injury following radical neck dissection was 94.8%, modified radical neck dissection 33.0%, and selective neck dissection 27.9%.
- Marginal mandibular-nerve injury following neck dissection is sparse.
- Patients should be informed about the risk of particular injuries to their spinal accessory nerve due to their specific subtype of neck dissection.
Remimazolam and Emergence Delirium
- In children undergoing tonsillectomy and adenoidectomy, administration of remimazolam 0.2 mg/kg at the end of the surgery resulted in a significantly lower likelihood of emergence delirium after sevoflurane anesthesia.
Neuromuscular Blockade and Neck Dissection
- Use of neuromuscular blockade intraoperatively during neck dissection was not associated with increased rates of iatrogenic cranial nerve injury.
Anesthetic Considerations for Endovascular Abdominal Aortic Aneurysm Repair
- EVAR was associated with lower short-term mortality but this benefit did not persist at the intermediate and long-term follow-ups.
- Patients undergoing EVAR have a higher incidence of major comorbidities and should undergo thorough preoperative assessment and optimization prior to the procedure.
Opioid-Free Total Intravenous Anesthesia and Postoperative Nausea and Vomiting
- Opioid-free TIVA is associated with a large reduction in relative risk of PONV compared with balanced anesthesia.
- Opioid-free TIVA was able to reduce PONV and the severity of PONV compared with inhalation anesthesia combined with opioids.
Combined Spinal Epidural Anesthesia for Laparoscopic Appendectomy
- Combined spinal epidural anesthesia is adequate and safe for elective laparoscopic appendectomy in healthy patients.
- Careful evaluation of the method is needed particularly in patients with compromised cardiorespiratory conditions.
Short-Term Outcomes of Combined Neuraxial and General Anesthesia
- Combined general and neuraxial anesthesia is associated with reductions in 90-day mortality and morbidity.
- This study highlights the role of combined general and neuraxial anesthesia as a safe and acceptable alternative to conventional GETA or LRA alone in CEA with similar rates of immediate and short-term complications and postoperative pain scores.### Surgical Pleth Index (SPI) Monitoring
- SPI is a monitoring tool that uses photoplethysmographic signals of finger arterioles to detect the balance between nociceptor activation and analgesia during general anesthesia.
- SPI-guided analgesia allows for appropriate doses of intraoperative analgesia with fewer adverse hemodynamic events, improving patient recovery and reducing postoperative pain and rates of adverse events.
- SPI values recorded before patient arousal can help predict the degree of postoperative pain and analgesic requirements.
managing Patients with Myasthenia Gravis (MG)
- MG is a neuromuscular disorder affecting muscarinic, nicotinic acetylcholine receptors, characterized by weakness and fatigability of the skeletal muscles.
- Patients with MG are often more sensitive to the depressive respiratory effects of benzodiazepines and opiates, and require special care during the perioperative period.
- Preoperative evaluation of MG patients should be based on disease severity according to Osserman's classification and treatment regimen, with extra attention paid to voluntary and respiratory muscles.
Anesthesia Management for MG Patients
- Neuromuscular blocking agents act by interrupting neuromuscular transmission at the level of nicotinic acetylcholine receptors at the motor end plate.
- Myasthenic patients are typically sensitive to nondepolarizing neuromuscular blockers, and resistant to depolarizing neuromuscular blockers (succinylcholine).
- Regional- and local anesthesia should be carried out using reduced doses of amide (rather than ester) as local anesthetics in order to avoid increased blood levels.
Non-Intubated Video-Assisted Thoracic Surgery (NI-VATS) Thymectomy
- NI-VATS thymectomy is a promising novel approach with numerous apparent benefits, but further data evaluation and a larger scale of patient outcome analysis are needed to determine exact indications and feasibility of the technique.
- Nonintubated spontaneous ventilation (NI-SV) anesthesia was feasible for VATS in the selected patients, with a greater incidence of intraoperative airway intervention events than intubated mechanical ventilation (I-MV) anesthesia.
Postoperative Pain Management
- The serratus anterior plane block (SAPB) shows an excellent performance in postoperative pain management in patients undergoing VATS, reducing pain scores, postoperative opioid consumption, and incidence of PONV.
