Anesthesia, essays and researches

Perioperative fluid management in elderly poses considerable challenge to the anesthesiologist. The conventional crystalloid loading may not be a preferred regime in this subgroup of patients since an exaggerated hemodynamic response is expected due to blunted sympathetic response and compromised cardiorespiratory system. ⋯ Ephedrine 30 mg i.m. given as pretreatment before SAB in elderly patients was more effective for the prevention of post-SAB hypotension.

The aim of the study was to compare the effect of mannitol (M) and hypertonic saline (HTS) on brain relaxation and electrolyte balance. ⋯ We concluded that HTS provided better brain relaxation than mannitol during elective supratentorial brain tumor surgery, without affecting ICU and hospital stay.

Ketamine was introduced commercially in 1970 with the manufacturer's description as a "rapidly acting, nonbarbiturate general anesthetic" and a suggestion that it would be useful for short procedures. With the help of its old unique pharmacological properties and newly found beneficial clinical properties, ketamine has survived the strong winds of time, and it currently has a wide variety of clinical applications. ⋯ The present article attempts to review the current useful applications of ketamine in anesthesia, pain and critical care. It is based on scientific evidence gathered from textbooks, journals, and electronic databases.

Inhalation anesthetics have many advantages for outpatient general anesthesia, such as minimal postoperative side-effects and rapid and full recovery. The aim of this randomized study was to compare the postoperative recovery time of sevoflurane and desflurane and to observe the effects of anesthesia on mental, psychomotor and cognitive functions and pain in outpatients undergoing arthroscopic surgery. ⋯ It has been determined that desflurane provided better quality and more rapid recovery than sevoflurane, and the return of cognitive functions in the early postoperative period was faster. In conclusion, both agents can apparently be used safely in outpatient anesthetic procedures.

Plexus block is the preferred anesthesia plan for upper limb surgeries. Among the known complications, hematoma formation following the vascular trauma is often occur but this complication is frequently underreported. ⋯ This case report attempts to highlight the essence of remaining vigilant postoperatively for first initial days after brachial plexus block, especially after failed or multiple attempts. Ultrasound guided technique in combination with nerve stimulator has proven to be more reliable and safer than traditional techniques.
