We report a case of deliberate ingestion of 12.5 g chloral hydrate in a 25-year-old psychiatric patient. Coma and life-threatening ventricular dysrhythmias were observed soon after ingestion. Repeated electrocardiographic examination was consistent with ischemic changes appearing on day 3. They were associated with segmental abnormal left ventricular wall motion by echocardiography. A coronary angiogram was performed and was normal. Toxic metabolites of chloral hydrate, trichloroethanol and trichloroacetic acid were found in the urine until day 7. This case illustrates that with halogenated aliphatic hydrocarbons, sustained changes in cardiac contractility may occur in addition to early life-threatening ventricular dysrhythmias.

Comparative Analysis of Preoperative Sedation Modalities: Oral Midazolam and Ketamine Versus Chloral Hydrate and Meperidine in Pediatric Tonsillectomy - A Randomized Clinical Trial.

Objective: A pre-anesthetic medication that is ideal for pediatric patients undergoing tonsillectomy should alleviate pediatric anxiety, facilitate the smooth induction of anesthesia, and have an analgesic effect for postoperative care. This study compared the effectiveness of an oral combination of midazolam and ketamine (MK) with an oral combination of chloral hydrate and meperidine (CM) as premedication in pediatric patients undergoing tonsillectomy.
Methods: This double-blind clinical trial study was conducted with 68 pediatric patients scheduled to undergo tonsillectomy.

Contemporary studies report nonconvulsive status epilepticus (NCSE) in Creutzfeldt-Jakob disease (CJD), based on benzodiazepine (BZP)-responsive epileptiform discharges on the electroencephalogram (EEG), with the following false syllogism: (1) intravenous (IV) administration of BZPs usually suppress ictal activity in NCSE; (2) in CJD, periodic sharp wave complexes (PSWCs) are suppressed by IV BZPs; (3) therefore, these patients have NCSE. This is a simplistic and invalid conclusion, because authors of 20th-century science reports have clearly shown that IV BZPs, short-acting barbiturates, and drugs with no antiseizure effects, such as chloral hydrate and IV naloxone, suppress PSWCs, but patients fall asleep with no clinical improvement. In contrast, IV methylphenidate transiently improves both the EEG and clinical states.

Background: Osteocytes are crucial for detecting mechanical stimuli and translating them into biochemical responses within the bone. The primary cilium, a cellular 'antenna,' plays a vital role in this process. However, there is a lack of direct correlation between cilium length changes and osteocyte mechanosensitivity changes.

- Chloral hydrate is a sedative used mainly in children for procedures like dental sedation and can be adapted for different patient needs due to a lack of commercially available age-appropriate forms.
- Researchers created a customizable oral liquid formulation of chloral hydrate using a suspending vehicle called PCCA SuspendIt, which is free from sugar, dyes, and gluten, to improve dosing accuracy for both pediatric and adult patients.
- The study aimed to develop and validate a stability-indicating assay using ultra-high-performance liquid chromatography (UPLC) to ensure the chemical stability of chloral hydrate at varying concentrations.

Background: In small dermatological surgeries for infant and child patients, it is required that the child be in a quiet state. However, general anesthesia not only requires the participation of professional anesthesiologists for surgery but also has a high cost and anesthesia risks. Parents have a low acceptance rate.
