“…Total post-operative pethidine consumption as pethidine was given as rescue analgesia in 25 mg intravenously when VAS ≥4. Sensory block was assessed post-operatively when the patient was fully awake by skin pinprick sensation at superficial cervical nerves dermatomal distribution [ 15 , 16 ]. Assessment of diaphragmatic dysfunction was conducted using ultrasound when there was desaturation (SaO2< 90%), tachypnea or difficult breathing, which was confirmed by chest x-ray if there was suspicion of diaphragmatic dysfunction [ 17 ].…”

“…The critical step of peripheral nerve block anesthesia is nerve identification. In the past, blind guidance of needle and nerve stimulation are often used [1]. Such methods have strict requirements for doctors' experience and require real-time patient feedback, which are difficult to achieve and prone to complications [2].…”

Ultrasound-guided nerve block anesthesia (UGNB) is a high-tech visual nerve block anesthesia method that can observe the target nerve and its surrounding structures, the puncture needle's advancement, and local anesthetics spread in real-time. The key in UGNB is nerve identification. With the help of deep learning methods, the automatic identification or segmentation of nerves can be realized, assisting doctors in completing nerve block anesthesia accurately and efficiently. Here, we establish a public dataset containing 320 ultrasound images of brachial plexus (BP). Three experienced doctors jointly produce the BP segmentation ground truth and label brachial plexus trunks. We design a brachial plexus segmentation system (BPSegSys) based on deep learning. BPSegSys achieves experienced-doctor-level nerve identification performance in various experiments. We evaluate BPSegSys' performance in terms of intersection-over-union (IoU), a commonly used performance measure for segmentation experiments. Considering three dataset groups in our established public dataset, the IoU of BPSegSys are 0.5238, 0.4715, and 0.5029, respectively, which exceed the IoU 0.5205, 0.4704, and 0.4979 of experienced doctors. In addition, we show that BPSegSys can help doctors identify brachial plexus trunks more accurately, with IoU improvement up to 27%, which has significant clinical application value.

“…Benzodiazepines or a small amount of propofol administered IV are preferred to terminate seizures. The use of benzodiazepine in premedication may be used to increase the seizure threshold, but respiratory depression may cause acidosis with its excess sedation, which increases the concentration of free drug in the serum [19].…”

Local anesthetics (LA) are one of the groups that block the transmission of sensory, motor and autonomic nerve impulses commonly used in clinical anesthesia. All local anesthetic molecules in clinical use consist of three parts: a lipophilic (aromatic) end, a hydrophilic (amine) end, and a chain that provides the connection between the ends. Physicochemical properties determine the clinical efficacy of local anaesthetics The part that determines the lipid solubility of local anesthetics is the aromatic ring. A higher dose of local anesthetics is required for cardiovascular system (CVS) toxicity. Hypertension, tachycardia and ventricular arrhythmia are the first of the diseases of CVS. Hypotension, arrhythmia, bradycardia and cardiac arrest develop as local anesthetics increase in blood. The symptoms of central nervous system (CNS) toxicity associated with LA are related to the plasma levels of drugs. Initially, there are drowsiness, dizziness, sedation, disorientation, tinnitus, nystagmus, metallic taste, nausea and vomiting. Then, restlessness, irritability, tremors and muscle twitches occur. After this, the tonic-clonic seizure and loss of consciousness develops, finally, apnea, cardiovascular collapse and coma. In the treatment of local anesthetic toxicity, it is recommended to provide airway, avoid the propofol if seizure occurs and treat with benzodiazepine. If cardiac arrest develops, it is recommended to switch to advanced life support, to reduce the given dose of adrenaline, to administer lipid emulsion (20%) and to respond to treatment if cardiopulmonary bypass is not provided.
