<abstract><title style='display:none'>Abstract</title> Postoperative shivering is a common complication of anaesthesia. Shivering is believed to increase oxygen consumption, increase the risk of hypoxemia, induce lactic acidosis, and catecholamine release. Therefore, it might increase the postoperative complications especially in high-risk patients. Moreover, shivering is one of the leading causes of discomfort for postsurgical patients. Shivering is usually triggered by hypothermia. However, it occurs even in normothermic patients during the perioperative period. The aetiology of shivering has been understood insufficiently. Another potential mechanism is pain and acute opioid withdrawal (especially with the use of short-acting narcotics). Besides that shivering is poorly understood, the gold standard for the treatment and prevention has not been defined yet. Perioperative hypothermia prevention is the first method to avoid shivering. Many therapeutic strategies for treating shivering exist and most are empiric. Unfortunately, the overall quality of the antishivering guidelines is low. Two main strategies are available: pharmacological and non-pharmacological antishivering methods. The combination of forced-air warming devices and intravenous meperidine is the most validated method. We also analysed different medications but final conclusion about the optimal antishivering medication is difficult to be drawn due to the lack of high-quality evidence. Nevertheless, control of PS is possible and clinically effective with simple pharmacological interventions combined with non pharmacological methods. However, to be consistent with the most up-to-date, evidence-based practice, future antishivering treatment protocols should optimize methodological rigor and transparency.</abstract>

Role of anaesthetic choice in improving outcome after cardiac surgery

<abstract><title style='display:none'>Abstract</title><bold>Background and Aim:</bold> Intra/post-operative shivering is frequently observed in parturients posted for elective cesarean delivery (C/D) under spinal anaesthesia. Several studies have advocated the anti-shivering effect of 5-HT3 antagonists, although none has revealed convincing results. The study aims to evaluate the prophylactic effect of a single intravenous dose of ramosetron (0.3 mg), compared with a placebo (N – normal saline), for the prevention of post-spinal shivering (PSS) during elective C/D.<bold>Method:</bold> The study comprised 80 parturients of the American Society of Anaesthesiologists (ASA) physical status I/ II, posted for elective C/D under spinal anaesthesia who were randomly divided into 2 equal groups; Group N: 0.9% normal saline (4 ml) immediately before induction of spinal anaesthesia and Group R: ramosetron (0.3 mg) intravenously diluted to 4 ml volume. Shivering at any time on a (0-4) scale and total dose of tramadol required for its treatment was recorded. The study also includes the recording of haemodynamic parameters and the incidence of early onset nausea and vomiting.<bold>Results:</bold> Statistically significant data was obtained while comparing incidence of shivering and maximum shivering at any time (P = 0.001). A lower incidence of early onset nausea and decreased total dose of tramadol was also observed in the ramosetron group.<bold>Conclusion:</bold> Ramosetron (0.3 mg) is advocated to be an effective drug in preventing post-spinal shivering among parturients posted for elective C/D. Moreover, its role in preventing maternal nausea together with better haemodynamic parameters further supported the advantageous role of ramosetron in our group of patients.</abstract>

To explore the incidence and risk factors, as well as mortality, in critically ill COVID-19 patients who developed pneumothorax (PTX) and/or pneumomediastinum (PNM).
</sec>
<sec><title style='display:none'>Methods</title>
A retrospective cohort study was undertaken to analyse data of all patients with moderate to severe COVID-19 disease who were either RTPCR positive or had a clinico-radiological diagnosis. The exposure group consisted of COVID-19 patients who presented with PTX/PNM, whereas the non-exposure group consisted of patients who did not develop PTX and/or PNM during the stay.
</sec>
<sec><title style='display:none'>Results</title>
Incidence of PTX/PNM was observed to be 1.9% among critically ill COVID-19 patients. 94.4% (17/18) of patients in the PTX group received positive pressure ventilation (PPV); the majority of these patients were on non-invasive ventilation when they developed PTX/PNM; only one patient was receiving conventional oxygen therapy. COVID-19 patients who developed PTX/PNM had 2.7 times higher mortality. A mortality rate of 72.2% was observed in COVID-19 patients who developed PTX/PNM.
</sec>
<sec><title style='display:none'>Conclusion</title>
Development of PTX/PNM in critically ill COVID-19 patients is associated with more severe disease involvement, and institution of PPV is an additional risk factor. Significantly high mortality was observed following PTX/PNM in critically ill COVID-19 patients and is an independent marker of poor prognosis in COVID-19 disease.

Incidence of postoperative nausea and vomiting (PONV) in susceptible patients can be unacceptably high (70–80% reported incidence). This study was designed to evaluate the effect of palonosetron and ondansetron in preventing PONV in high-risk patients undergoing gynaecological laparoscopic surgery.
</sec>
<sec><title style='display:none'>Methodology</title>
In this randomised, controlled, double-blind trial, nonsmoking females 18–70 years and weighing 40–90 kg, scheduled for elective laparoscopic gynaecological surgeries, were enrolled into the ondansetron (Group A, n=65) or palonosetron (Group B, n=65) group. Palonosetron (1 mcg/kg 4) or ondansetron (0.1 mg/kg 4) were administered just before induction. Postoperatively, incidence of nausea, vomiting, PONV (scored on a scale of 0–3), need for rescue antiemetic, complete response, patient satisfaction, and adverse effects were evaluated for up to 48 h following surgery.
</sec>
<sec><title style='display:none'>Results</title>
The overall PONV scores and postoperative nausea score during 0–2 h and 24–48 h were comparable, but PONV scores (P=0.023) and postoperative nausea scores (P=0.010) during 2–24 h were significantly lesser in Group B compared to Group A. There was no statistically significant difference in the postoperative vomiting score or retching during 0–48 h. The amount of first-line rescue antiemetic used during 2–24 h was significantly higher in Group A (56%) than in Group B (31%) (P=0.012; P&lt;0.05). Complete response to the drug during 2–24 h was significantly higher (P=0.023) in Group B (63%) compared to Group A (40%), whereas response was comparable during 0–2 h and 24–48 h. Both groups had comparable incidences of adverse effects and patient satisfaction scores.
</sec>
<sec><title style='display:none'>Conclusion</title>
Palonosetron has superior antinausea effect, less need of rescue antiemetics, and lesser incidence of total PONV in comparison to ondansetron during 2–24 h and comparable effect to ondansetron during the 0–2 h and 24–48 h postoperative periods in high-risk patients undergoing gynaecological laparoscopic surgery.

A large number of spinal deformities with severe pain are treated with complex and traumatic spinal surgeries. The objectives of our study were to test the hypotheses that bilateral erector spinae plane block (BESPB) as a component of combined anaesthesia for spinal surgeries decreases the quantity of opioid analgesic used and reduces hyperalgesia in comparison with general anaesthesia. We additionally proposed the use of serum testosterone, cortisol, C-reactive protein (CRP), and glucose levels as laboratory markers for hyperalgesia.
</sec>
<sec>
<title style='display:none'>Methods</title>
Fifty-two patients who underwent posterior transpedicular fixation of the spine were randomly assigned to either general anaesthesia – control group (CG) – or combined anaesthesia with BESPB – study group (SG). The main outcomes sought were quantity of opioid analgesic perioperatively; hyperalgesia measured with mechanical pain thresholds; and testosterone, cortisol, CRP, and glucose serum levels before and after surgery.
</sec>
<sec>
<title style='display:none'>Results</title>
The quantity of fentanyl and morphine was lower in SG in comparison with CG. There was no difference in mechanical pain thresholds in the SG cohort as opposed to CG, where mechanical pain thresholds were lower on the fifth day after surgery. No difference was found before and after surgery in testosterone, cortisol, CRP, and glucose levels in SG. In the CG, the level of testosterone was significantly lower than baseline; the levels of cortisol, CRP, and glucose were significantly higher than baseline on the fifth day after surgery.
</sec>
<sec>
<title style='display:none'>Conclusion</title>
Bilateral erector spinae plane block as a component of combined anaesthesia for spinal surgeries reduces the quantity of opioid analgesic used and hyperalgesia. Also, we can propose to use the serum testosterone, cortisol, CRP, and glucose levels as the laboratory markers of hyperalgesia.

Pyroglutamic acidosis (PGA) is an underrecognized entity characterised by raised anion gap metabolic acidosis (RAGMA) and urinary hyper-excretion of pyroglutamic acid. It is frequently associated with chronic acetaminophen (APAP) ingestion. We report the case of a 73-year-old man with invasive pulmonary aspergillosis treated with voriconazole and APAP for analgesia with a cumulative dose of 160 g over 40 days. PGA was suspected as he developed severe RAGMA and common causes were excluded. Diagnosis was confirmed via urinary organic acid analysis which showed significant hyper-excretion of pyroglutamic acid. APAP was discontinued, and N-acetylcysteine (NAC) was administered. His RAGMA rapidly resolved following treatment.

We searched PubMed, Google Scholar, and the Cochrane Library from inception to October 2021 for randomised controlled trials written in English. We included studies on adult populations undergoing abdominal surgery. The primary outcomes of our meta-analysis were postoperative pain intensity and postoperative opioid consumption. Data analysis was conducted using the Review Manager software (RevMan, v. 5.4). Statistical heterogeneity was estimated by the I2 statistic. The methodological quality of the included studies was assessed using the Oxford quality scoring system (Jadad Scale).
</sec>
<sec>
<title style='display:none'>Results</title>
Eight randomised controlled trials (RCTs) in English with a total of 386 patients were included in this meta-analysis. Patients in the RSB group did not consume fewer anaesthetics and opioids after abdominal surgery when compared with patients in the control group. In addition, postoperative pain intensity (out of 10) was not lower in the RSB group when compared with the control group. Finally, RSB did not improve the time to the first opioid/analgesic (min) compared with the non-RSB option.
</sec>
<sec>
<title style='display:none'>Conclusion</title>
There is no statistically significant evidence in favour of RSB over non-RSB in reducing anaesthetics and opioid consumption, postoperative pain intensity, and increasing time to first opioid/analgesic.

Rectus Sheath Block in Abdominal Surgery: A Systematic Review with Meta-Analysis

Fluid management in the perioperative period is a grey zone in clinical practice of late. Looking back on previous practices, static parameters were the only options. Now, dynamic parameters indicating fluid responsiveness have become a significant part of goal-directed fluid therapy (GDFT). However, the efficacy of this approach has yet to be established in neurosurgery cases where patients are already on lot of diuretics, thus making fluid management more challenging. The present study aims to determine the efficacy of the Pleth Variability Index (PVI) with pulse pressure variation (PPV) in guiding GDFT in patients undergoing neurosurgery for supra-tentorial intracranial space occupying lesions (ICSOLs), in the form of a randomised controlled trial.
After randomisation, the patients were categorised into either PVI or PPV groups. Both received a baseline 2 ml/kg/h Lactated Ringer’s (RL) infusion. Additional fluid boluses consisted of 250 ml of colloid infused over a 10 min period if PVI was &gt; 15% or PPV was &gt; 13% for at least five minutes. The primary outcome was to determine the serum lactate difference between preoperative and postoperative values, which could fairly predict fluid deficit leading to inadequate perfusion.
A total of 74 patients were analysed. Both PVI- and PPV-guided GDFT strategies showed no significant difference in the postoperative lactate values, with a P-value of 0.18. Similarly, the mean total fluid administered, mean blood loss, length of CCU stay, and emetic and hypotension episodes also showed no significant differences among the groups with P-values of 0.41, 0.78, 0.25, 0.30, and 0.67, respectively.
For patients undergoing neurosurgery (supratentorial ICSOLs), PVI seems to guide GDFT comparably to PPV regarding tissue perfusion and postoperative complications. However, both the parameters had low sensitivity and specificity, with an area of curve of 0.577 for PPV and 0.423 for PVI, as far as GDFT was concerned.

In critical patients, generally, microorganisms originating from nasal cause Ventilator-Associated Pneumonia (VAP). This systematic review was aimed to identify the toothbrush U shape model usage, in potentially decrease the prevalence of ventilator-associated pneumonia among patients in intensive care units. Search strategy identified 15 potentially eligible articles, were 7 RCTs, 4 Meta-analysis, and 4 Observational studies. A total of 15 studies demonstrated the use of toothbrushing and chlorhexidine in mechanically ventilator patients in preventing VAP. Ten studies found positive association between toothbrushing and the use of chlorhexidine in preventing VAP. However, there were 5 studies that did not reveal an additional decrease of VAP incidence either of CHX and only toothbrushing or combination thereof. We cautiously assumed that toothbrushing and chlorhexidine might reduce VAP but the implementation of brushing should be taken into reconsideration in the terms of maintaining it.
