Inhalational Anaesthesia

AbstractMyocardial protection with volatile anesthetic agents have been suggested by multiple studies. These studies, however, are scattered and are often limited to a particular aspect of cardiac anesthesia. Older inhalational agents like halothane is known to cause significant hepatic damage in patients undergoing long duration surgeries while isoflurane is known to have marked vasodilating properties that also affects the coronary arteries leading to coronary “steal” phenomenon. Additionally, newer agents, like sevoflurane and desflurane, have shown more prominent cardioprotective effects than older agents. We searched ScholarOne, Medline, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library. The medical subject headings (MeSH) terms “anaesthesia, inhalational,” “anaesthesia, intravenous, or TIVA,” and “Cardiac anaesthesia or Cardiac Surgery” were used. Additional studies were identified by review of the reference sections of all eligible studies. The aim of this review article is to bring together the evidences with newer inhalational agents and provide a holistic view of their benefits and shortcomings in cardiac anesthesia.

Gynaecological surgery is of high emetogenic potential and both total intravenous anaesthesia (TIVA) and prophylactic antiemetic therapy may reduce the incidence of postoperative nausea and vomiting (PONV). We studied 144 patients scheduled for day-case gynaecological laparoscopy in a randomized trial comparing balanced inhalational anaesthesia and prophylactic dolasetron (group I+D) with propofol TIVA and dolasetron (group T+D) or TIVA alone (group T). The primary outcome of “complete response” (no vomiting, no treatment for PONV) was not significantly different among groups (34%, 51%, 32%; groups I+D vs T+D vs T, P=0.12). During the first hour after surgery, group I+D had nausea of greater severity (P<0.03). During hospital admission, group T had more vomiting (P<0.03). From discharge until 24 hours postoperatively, 55% of group I+D experience nausea and 38% vomited. The incidence and severity of nausea were significantly lower in the TIVA groups (P<0.04 and < 0.05 respectively). There were no significant differences between groups T+D and T, although comparing all groups the complete response rate was highest and the post-discharge incidence and severity of nausea lowest in group T+D. In conclusion, propofol TIVA, with or without dolasetron, reduced postoperative nausea, but not perioperative vomiting or antiemetic requirement, when compared with inhalational anaesthesia plus dolasetron.

Persistent Headache

A 31-years-old patient, pregnant at 32 weeks of gestation presented to our triage unit with complaint of gradually progressive persistent headache that started 1 day earlier and was unresponsive to all analgesics. Her history was insignificant for any major medical or surgical events and the pregnancy course was smooth as well. Her lab results and obstetric ultrasound were reassuring. During magnetic resonance imaging examination, the patient suddenly deteriorated after giving her an inhalational anaesthesia for sedation. She became unconscious. She was intubated, mechanically ventilated, and put-on cardiovascular support. Brain imaging then revealed Brain Stem (BS) herniation and diffuse brain oedema. She was announced dead with intrauterine foetal death. A late diagnosis of cerebral venous thrombosis was established. This caused BS herniation through increased intracranial pressure, which was iatrogenically augmented by administering inhalation anaesthesia. Keywords: cerebral vein; thrombosi; thrombophilia; pregnancy; headache; magnetic resonance imaging; brain stem herniation.

The Mean

Optic nerve sheath diameter measurement is a simple, non-invasive and yet accurate intracranial pressure (ICP) assessment technique during laparoscopic surgery. The pneumoperitoneum induced by insufflating carbon-dioxide and steep angle of trendelenburg position is associated with physiological changes resulting in increased ICP during laparoscopic surgery. We aimed to observe the changes of ONSD (surrogate marker of ICP) following the use of total intravenous anaesthesia in comparison to desflurane during laparoscopic surgery.Patients scheduled for elective laparoscopic surgery were randomly assigned to the TIVA or DES group in this randomized study. Ultrasonographic measurements of ONSD were conducted before administration of anaesthesia (T0), 10 mins, 30 mins, 1 hr after the trendelenburg position (T1,T2,T3), 5mins after resuming the supine position (T4) and at post-anaesthetic care unit (T5). The primary outcome measure was the comparison of the mean ONSD of both the eyes of the patients of both the groups that is TIVA versus DES (inhalational anaesthetic) group.A total of 60 patients were analysed in our study. The mean ONSD value at T1, T2, T3 and T4 (for right eye p=0.002,0.001,&#60;0.01,0.03 respectively and for left eye p=0.004,&#60;0.01,&#60;0.01,0.02 respectively) were significantly lower for patients in TIVA group as compared with those in DES group.Our result suggests that TIVA may be a better option than inhalational anaesthesia to prevent rise in intracranial pressure in patients undergoing laparoscopic surgery and preventing devastating complications caused by raised intracranial pressure in succeptible patients.
