Ideal intubating position (modified chevalier Jackson position) is
It is also called morning sniffing position or barking dog position. Explanation Prior to direct laryngoscopy and intubation, the patient is placed in the sniffing position which consists of cervical flexion with atlantooccipital extension. This is to ensure a line of sight from the mouth to the larynx so that intubation can be performed with ease. Cervical flexion of 35 degrees is provided by elevating the patient's head by 7-9 cm (folded sheet under the head). This aligns the pharyngeal and laryngeal axes. Atlantooccipital extension is provided by the head tilt. This brings into alignment the visual axis of the mouth with that of pharyngeal and laryngeal axes. Adequacy of head elevation can be estimated by checking the horizontal alignment between external auditory meatus and sternal notch.

Size of the laryngeal mask airway for normal adults
Voyagis have proposed an alternative method of size selection for the laryngeal mask airway (LMA) based on a common misconception that the No. 3 is for females and the No. 4 for males. In fact, their new proposal strongly reflects current European practice, which is to use a No. 4 for normal adults and a No. 5 for large adults and to use the No. 3 rarely. We consider, however, that further conclusive trials are required before the manufacturer's weight-based recommendations are altered. Judging the correct size of LMA can be difficult since the relationship between gender, weight, height, and upper airway geometry appears inconsistent. No factors have yet been identified that give an easy measurement of potential pharyngeal volume directly correlating with appropriate LMA size, and certainly, there is no known anatomical difference between the male and the female adult or child pharynx at a given weight. Some practitioners consider that the smaller sizes are satisfactory for spontaneous ventilation since a less effective seal is required. However, too small a mask may still result in local soft tissue damage due to poor fit around the laryngeal inlet or misplacement into the upper oesophagus or the glottic inlet. The problems associated with insertion of too large a mask (airway obstruction, airway reflex activation) are probably fewer than those associated with insertion of too small a mask.

Sevoflurane is the inducing agent of choice in children . Cardiovascular stability in decreasing order : Isoflurane(nost stable)>desflurane>Sevoflurane>Halothane>Enflurane. Halothane suppresses baroreceptor reflex and causes tachycardia (Arrythmogenic -by sensitising the hea to catecholamines) Enflurane is most cardiovascular unstable agent Isoflurane is the most cardiostable inhalational agent as cardiac output is best maintained by reflex tachycardia as protective baroreceptor reflex is minimally inhibited. Among Isoflurane and sevoflurane, sevoflurane is the agent of choice in children. Ref.:Morgan 4th/e p 929

Best site for going spinal anaesthesia is interveebral space between.
The spinal canal contains the spinal cord with its covering (the meninges), fatty tissue and venous plexus. The meninges are composed of three layers: the pia mater, the arachnoid mater and the Dura meter. The spinal subdural space is poorly demarcated. The epidural space is a better defined potential space within the spinal canal that is bounded by the Dura meter and ligamentum flavum. There is cerebrospinal fluid between pia meter and Archnoid meter and this space is called sub arachnoid space. The spinal cord normally extends from the foramen magnum to the level of L1 in adults. so in adults we can give spinal anesthesia below this level in L2/L3, L3/L4. L2/L3 IS BETTER SPACE In children the spinal cord ends at L3 and moves up with age. The blood supply to the spinal cord and nerve roots is derived from a single anterior spinal aery and pair posterior aeries.

Arrange Mapelson circuit for spontaneous ventilation in an adult from best to worst
During spontaneous ventilation, alveolar gas containing Co2 will be exhaled into the breathing tube or directly vented through an open APL valve. Before inhalation occurs, if the fresh gas flow exceeds alveolar minute ventilation, the in flow of fresh gas will force the alveolar gas remaining in the breathing tube to exit from the APL valve. Because a fresh gas flow equal to minute ventilation is sufficient to prevent rebreathing, the Mapelson a design is the most efficient for spontaneous ventilation

Least effect on myocardial contractility
Ans:D i.e. Isoflurane. CARDIAC EFFECTS OF ANESTHETIC AGENTS :Anticholinergic agents - Atropine/glycopyrrolate: will cause an increase in hea rate, contractility, cardiac output and myocardial oxygen consumption. Often there will be no changein blood pressure and a decrease in right atrial pressure.Thiopental - BarbiturateReduction in blood pressure - peripheral vasodilation is the main action. Compensatory rise in hea rate - barorecptor response. Commonly associated with ventricular arrhythmias .BenzodiazepinesMidazolam and diazepam: Cause little or no direct myocardial depressant effects.Hypnotics- Etomidate: no direct myocardial depression. Safe to use with cardiac, critical and septic patients. .Mu opioids- Fentanyl is a pure mu agonist causes dose dependant bradycardia (increase in vagal tone). Mixed agonist/antagonist agents= Buprenorphine: a paial mu agonist/antagonist. Slow onset of action, duration of 6-8 hours. Cardiovascular depression and respiratory depression not as profound as pure mu agonists. Butorphanol: paial agonist/antagonist. Similar to buprenorphine in cardiovascular/respiratory effects. Dissociative Agents:Ketamine- Hea rate and aerial pressure increase due to an increase in sympathetic tone .Inhalational Anesthetics: Isoflurane and sevoflurane preserved cardiac index, and isoflurane and fentanyl-midazolam preserved myocardial contractility at baseline levels in this group of patients with congenital hea disease. Halothane depressed cardiac index and myocardial contractility.

Minimum &;starvation time&; required in general anaesthesia
Traditionally, patients are considered to be at risk if their gastric volume is greater than 25 mL (0.4 mL/kg) and their gastric pH is less than 2.5. Some investigators believe that controlling acidity is more impoant than volume and that the criteria should be revised to a pH less than 3.5 with a volume greater than 50 mL. Patients who have eaten immediately prior to emergency surgery are obviously at risk. Traditionally, "NPO after midnight" implied a preoperative fast of at least 6 h. The current opinion allows clear liquids until 2 h before the induction of anesthesia. According to the American Society of Anesthesiologists (ASA) guideline, breast milk is permitted up to 4 h before anesthesia. Infant formula, nonhuman milk, and a light meal are permitted up to 6 h before induction. Patients consuming a heavy meal including meat, fats, and fried foods should fast for 8 h. Ceain patient populations are paicularly likely to have large volumes of acidic gastric fluid: patients with an acute abdomen or peptic ulcer disease, children, the elderly, diabetic patients, pregnant women, and obese patients. Fuhermore, pain, anxiety, or opioids may delay gastric emptying. Note that pregnancy and obesity place patients in double jeopardy by increasing the chance of aspiration (increased intraabdominal pressure and distoion of the lower esophageal sphincter) and the risk of aspiration pneumonia (increased acidity and volume of gastric contents). Aspiration is more common in patients undergoing esophageal, upper abdominal, or emergency laparoscopic surgery. Ref: Morgan & Mikhail&;s clinical anesthesiology 6e

A 25 year old G2P, at 39 weeks gestation is electing to have spinal anaesthesia for a repeat cesarean section. 5 minutes after bupivacaine spinal injection, the patient becomes hypotensive and is complaining of tingling in her fingers with subjective difficulty breathing. Her oxygen saturation remains 100% and blood pressure in 90/60 mmHg The most likely etiology is.
In pregnancy, CSF volume is decreased, thereby decreasing dose requirement of local anaesthetic. This facilitates spread of local anaesthetic when spinal anaesthesia is given. Option D would have been correct, if question mentioned Epidural anaesthesia.

Management of prolonged Scoline apnea is by
Suxamethonium apnea and phase 2 block both are managed with mechanical ventilation till recovery. The mainstay treatment for succinylcholine apnea due to atypical pseudocholinesterase is to continue mechanical ventilation until muscle function returns to normal by clinical signs. Administration of neostigmine is controversial as the effects may be transient, possibly followed by intensified neuromuscular blockade. Fresh frozen plasma can augment the patient's endogenous plasma pseudocholinesterase activity but is not recommended because of the risk of iatrogenic viral infectious complications. If human plasma cholinesterase is available, it can be given to reverse neuromuscular blockade. Hence, the best option here would be to continue mechanical ventilation.

Tec 6 vaporizer is used with.........
The most common such vaporizer is the Ohmeda Tec 6, designed specifically for use with desflurane. Desflurane has two physical propeies, making it unsuitable for use with a conventional vaporizer. First, it has a very high SVP (88.5 kPa at 20degC). A conventional vaporizer would require high fresh gas flows to dilute it to within clinically useful concentrations, making it uneconomical. Secondly, it has a low boiling point (23.5degC). At room temperature, it will intermittently boil resulting in large fluctuations in agent delivery. When boiling, there will be excessive agent delivery; however, it will then cool due to a large loss of latent heat of vaporization, resulting in an exponential decrease in SVP and under-delivery of agent. The Ohmeda Tec 6 overcomes these problems by using an electrical filament that heats the desflurane to 39degC, raising its SVP to 194 kPa, that is, nearly 2 atm. In addition to providing a stable SVP, this high pressure removes the need for a pressurized carrier gas--instead, the fresh or diluent gas is entirely separate from the vaporizing chamber

Drugs only blocks sacral nerve roots and perineal anaesthesia is achieved.Since thoracic and lumbar spinal nerves are not blocked it has is no haemodynamic alteration. Caudal is the other name of sacral epidural anaesthesia commonly done in < 7 yrs old children since it is easy to approach is sacral epidural space because of unfused sacral hiatus. Caudal anesthesia requires identification of the sacral hiatus.

The optimal granule size of soda lime is
The size of the soda lime granules is 4-8 mesh (i.e. will pass through a mesh of 4-8 strands per inch in each axis or 2.36-4.75 mm). Soda lime consists of 4% NaOH, 1% KOH, 14-19% H2O, and the remainder Ca (OH)2. In addition, small amounts of silica or kieselguhr are added for hardening, and to reduce the formation of dust. Absorbents are supplied in pellets or granules. Small granules provide greater surface area but at the cost of increased resistance The most frequently used size of soda lime granule is 4-8 mesh (i.e., 0.25-inch to 0.125-inch diameter). In theory, 100 g of CO2absorbent (soda lime) can absorb 26 L of CO2.

A patient after undergoing thoracotomy complains of severe pain. He can be managed by
Orotracheal intubation Patients with severe maxillofacial trauma and with low Sp02 even on oxygen suggests severe airway compromise or obstruction. In these cases emergency airway management is essential. The patient require immediate oxygen. - These patients needs to be intubated immediately. - But an impoant point to note is that severe maxillofacial trauma makes intubation very difficult. -Some believe that nasotracheal intubation is contraindicated in patients with severe maxillofacial injury because nasotracheal intubation in these patients can result in nasocranial intubation or severe nasal hemorrhage. - Nasotracheal intubation is absolutely contraindicated in patients with midfacial injury and C.S.F. rhinorrhoea. Orotracheal intubation in patients with severe maxillofacial injury In patients with severe maxillofacial injuries orotracheal intubation is also difficult. Presence of blood clots, .fractures make the passage of the tube quite difficult. Moreover when the surgeons perform operation for mandibular or maxillary fractures they wires both these together. If surgery is required with severe maxillofacial injury surgeons usually prefer nasotracheal intubation or tracheostomy. Tracheostomy in patient with severe maxillofacial injury : ? Tracheostomy does not have much role in "emergency airways management". - Tracheostomy is a time taking procedure compared to intubation. - If the airways of the patient is severely compromised and he requires immediate oxygenation, tracheostomy has no role. - Immediate oxygenation can only be delivered by rapid intubation. In case, intubation is impossible, cricothyroidotomy is an alternative. -In emergency management of the airway, cricothyroidotomy is done if intubation is not possible. Tracheostomy is only done when immediate oxygen requirements are taken care of and a surgical procedure is planned. In the question the Sp02 of the patient is 80% when on oxygen. He requires immediate emergency management of the airway which can be achieved through intubation, If intubation is impossible, cricothyroidotomy is an alternative. The better option of intubation in this patient is orotracheal intubation. The ideal management in this patient is cricothyroidotomy. Since that is not mentioned in the question intubation in the next best option. "Orotracheal intubation would be preferred over nasotracheal intubation in these cases"

Inducing agent of choice in DIC
The cardiovascular stimulatory effects make ketamine a desirable drug for the induction of anesthesia in unstable cardiovascular patients suffering from hypovolemia, hemorrhagic shock, or cardiovascular depression in sepsis. Ketamine bronchodilation and profound analgesia allowing the use of high oxygen concentrations make ketamine an excellent choice for induction of anesthesia in patients with reactive airway disease. Patients who have sustained trauma with extensive blood loss are typical candidates for rapid-sequence anesthesia induction with ketamine. Patients with septic shock also may benefit from ketamine. The intrinsic myocardial depressant effect of ketamine may manifest in this situation if trauma or sepsis has caused depletion of catecholamine stores before the patient's arrival in the operating room. The use of ketamine in these patients does not obte the need for appropriate preoperative preparation, including restoration of intravascular blood volume.

Most impoant factor determining the affect of anaesthetic agent on fetus
All the given options determined the effect of anaesthetic on fetus. But, duration of pregnancy is the most impoantAlmost all anaesthetic agents can be potentially teratogenicDay 15th to day 60 is the most critical period.(Refer: Morgan and Mikhail's Clinical Anaesthesiology, 5th edition, pg no. 846)
