ReviewFactors that affect the onset of action of non-depolarizing neuromuscular blocking agents.
Neuromuscular blockade plays an important role in the safe management of patient airways, surgical field improvement, and respiratory care. Rapid-sequence induction of anesthesia is indispensable to emergency surgery and obstetric anesthesia, and its purpose is to obtain a stable airway, adequate depth of anesthesia, and appropriate respiration within a short period of time without causing irritation or damage to the patient. There has been a continued search for new neuromuscular blocking drugs (NMBDs) with a rapid onset of action. ⋯ Anesthesiologists should be aware of the use of NMBDs in the management of anesthesia. The choice of NMBD and determination of the appropriate dosage to modulate neuromuscular blockade characteristics such as onset time and duration of neuromuscular blockade should be considered along with factors that affect the effects of the NMBDs. In this review, we discuss the factors that affect the onset time of NMBDs.

Postdural puncture headache (PDPH) is a common complication after inadvertent dural puncture. Risks factors include female sex, young age, pregnancy, vaginal delivery, low body mass index, and being a non-smoker. Needle size, design, and the technique used also affect the risk. ⋯ Various other prophylactic and treatment interventions have been suggested. However, due to a lack of conclusive evidence supporting their use, the potential benefits of such interventions should be weighed carefully against the risks. This article reviews the current literature on the diagnosis, risk factors, pathophysiology, prevention, and treatment of PDPH.

ReviewDual antiplatelet therapy and non-cardiac surgery: evolving issues and anesthetic implications.
Dual antiplatelet therapy (DAPT) consisting of aspirin plus a P2Y12 inhibitor (clopidogrel, prasugrel, or ticagrelor) is imperative for the treatment of acute coronary syndrome, particularly during the re-endothelialization period after percutaneous coronary intervention (PCI). When patients undergo surgery during this period, the consequences of stent thrombosis are far more serious than those of bleeding complications, except in cases of intracranial surgery. The recommendations for perioperative DAPT have changed with emerging evidence regarding the improved efficacy of non-first-generation drug (everolimus, zotarolimus)-eluting stents (DES). ⋯ In emergent or urgent surgeries that cannot be delayed beyond the recommended period after PCI, proceeding to surgery with continued DAPT should be considered. For intracranial procedures or other selected surgeries in which increased bleeding risk may also be fatal, cessation of DAPT (possibly with continuation or minimized interruption [3-4 days] of aspirin) with bridge therapy using short-acting, reversible intravenous antiplatelet agents such as cangrelor (P2Y12 inhibitor) or glycoprotein IIb/IIIa inhibitors (tirofiban, eptifibatide) may be contemplated. Such a critical decision should be individually tailored based on consensus among the anesthesiologist, cardiologist, surgeon, and patient to minimize both ischemic and bleeding risks.

ReviewPractice guidelines for propofol sedation by non-anesthesiologists: the Korean Society of Anesthesiologists Task Force recommendations on propofol sedation.
In South Korea, as in many other countries, propofol sedation is performed by practitioners across a broad range of specialties in our country. However, this has led to significant variation in propofol sedation practices, as shown in a series of reports by the Korean Society of Anesthesiologists (KSA). This has led the KSA to develop a set of evidence-based practical guidelines for propofol sedation by non-anesthesiologists. ⋯ Draft guidelines were scrutinized and discussed by advisory panels, and agreement was achieved via the Delphi consensus process. The guidelines contain 33 recommendations that have been endorsed by the KSA Executive Committee. These guidelines are not a legal standard of care and are not absolute requirements; rather they are recommendations that may be adopted, modified, or rejected according to clinical considerations.

Patient safety has become an important policy agenda in healthcare systems since publication of the 1999 report entitled "To Err Is Human." The paradigm has changed from blaming the individual for the error to identifying the weakness in the system that led to the adverse events. Anesthesia is one of the first healthcare specialties to adopt techniques and lessons from the aviation industry. ⋯ Despite holding relatively advanced medical technology and comparable safety records, the Korean health industry has little understanding of the systems approach to patient safety. Because implementation of the existing system and program requires time, dedication, and financial support, the Korean healthcare industry is in urgent need of developing patient safety policies and putting them into practice to improve patient safety before it is too late.
