Mid-axillary transversus abdominis plane block (TAP-B) and subcostal TAP-B have become well-known blocks to provide considerable analgesia for abdominal surgery. However, proper approach and adequate volume of injectate have not still been clarified. In this study, a combination of mid-axillary TAP-B and subcostal TAP-B was performed in cadavers to establish the spread of injectate and segmental nerve involvement. ⋯ This study demonstrated that the combination of ultrasound-guided mid-axillary TAP-B and subcostal TAP-B involve T8-L1 nerves. This technique can be used not only in lower abdominal surgery but also in upper abdominal surgery.

The head-down tilt is thought to increase the cross-sectional areas (CSAs) of the vein in central venous catheterization. In this study, the effectiveness of the head-down tilt was investigated in children. ⋯ The head-down at 10 degrees effectively increased the CSA when the IJV flattening ratios at 0 degrees was more than 0.3 in group H.

Anticholinesterase, such as neostigmine, was used to be a standard drug at the end of surgery for reversal of nondepolarizing neuromuscular block. Neostigmine decreases the metabolism of acetylcholine (ACh) at the neuromuscular junction and allows its concentration to increase and overcome the effect of the muscle relaxant. But this approach is ineffective against profound block. ⋯ In addition to donepezil, two other cholinesterase inhibitors have recently been approved for the treatment of AD patients. The drugs have slightly different pharmacological properties, but they all work by inhibiting the breakdown of acetylcholine, an important neurotransmitter associated with memory, by blocking the enzyme acetylcholinesterase. Donepezil can also reverse opioid-induced respiratory depression.

Ambulatory electroconvulsive therapy (ECT) is prevailing nowadays because of its lower cost and less disruption of the patient's social activity. We evaluated the safety and recovery profiles of general anesthesia for acute-phase or continuation/maintenance ambulatory ECT. ⋯ General anesthesia for ambulatory ECT with our protocol was proven to be safe without causing serious complications.

Ketamine was first used in humans over 40 years ago. Since then, ketamine has not been always used in anesthetic practice because of its unique pharmacological properties such as sympathomimetic or psychomimetic effect. ⋯ These pharmacological actions are based on property of ketamine as an NMDA receptor antagonist. We describe basic NMDA receptor function and possible action of ketamine via the receptor.
