Lavender aromatherapy: Its effect on preoperative anxiety and propofol requirement for anesthesia

Background & objective: Preoperative anxiety is a natural human psychology, and the physicians usually prescribe tranquillizers to allay the anxiety of their anxiety. Various other means have also been employed for this purpose. We aimed to investigate the impact of lavender aromatherapy on preoperative anxiety and propofol requirement at induction of anesthesia.
 Methodology: A total of 108 female patients were enrolled in the study, and their anxiety levels were evaluated using the Visual Analogue Scale (VAS) at three different time points. Patients were randomly divided into two groups. Group A (Lavender Group) patients were given lavender aromatherapy via a cotton strip infused with two drops of 100% pure lavender essential oil, while the patients in Group B (Control Group) had no aromatherapy.
 Results: The results showed that the lavender aromatherapy significantly reduced anxiety in Group A (P < 0.001) compared to Group B, and the mean differences of VAS scores for all anxiety assessments were also significantly reduced in Group A (P < 0.000). In addition, the mean total amount of propofol required was significantly less in Group A than in Group B (118.46 ± 40.01 vs 140.38 ± 35.29 mg; P = 0.003), while the mean duration to reach loss of consciousness was similar in both groups.
 Conclusion: The findings of our study suggest that lavender aromatherapy can be a simple, safe, and cost-effective way to reduce preoperative anxiety and decrease the amount of propofol required for the induction of anesthesia. Therefore, the use of lavender aromatherapy may be a valuable addition to the preoperative care of patients undergoing elective surgeries.

P 023: Idiopathic left fascicular ventricular tachycardia in pregnancy

Ventricular tachycardia (VT) can occasionally cause complications in pregnancy. In structurally normal heart, VT that arises in the left ventricle is uncommon and is termed as idiopathic left fascicular VT (ILVT). We report a case of 32-year-old lady, gravida 4 para 3 who presented to us at 34 weeks of pregnancy with symptomatic stable cardiac arrythmia with heart rate of 160 beats per minute. Electrocardiogram showed wide complex tachycardia with positive initial R wave at aVR and capture beats suggestive of ILVT. Echocardiogram was normal. She received IV verapamil 25 mg in total which failed to revert to sinus rhythm and hence, she underwent emergency Caesarean section followed by synchronized cardioversion urgently in operation theatre. Post cardioversion ECG showed sinus rhythm with memory T waves at chest leads. She was scheduled radiofrequency ablation later. This case highlights the importance of attaining the diagnosis of ILVT with distinctive ECG changes. Left ventricular outflow tract (LVOT) VT morphology depends on the site of origin, with either LBBB or early precordial transition in leads V1 to V2 or RBBB pattern in V1 with broad monophasic R in the precordial leads. In addition, there will be an R:S amplitude ratio of 30% or more or an R:QRS duration ratio of 50% in leads V1–2 with other features like capture beats and fusion beats. ILVT responds well with verapamil and can be cured with cardiac ablation, with success rates of more than 90%. ILVT though difficult to diagnose, it has distinctive ECG features which can lead to its diagnosis for appropriate treatment to be given accordingly. ILVT in pregnant patients generally has a good prognosis.

Mycological Methods for Routine Air Sampling and Interpretation of Results in Operating Theaters

Many infectious diseases are transmitted via the air and are, therefore, particularly difficult to combat. These infections include various invasive mycoses caused by molds. The usual route of infection is the inhalation of conidia. In hospitals, infection can also occur through the deposition of conidia in otherwise sterile anatomical sites during surgical and other invasive procedures. Therefore, knowledge of airborne mold concentrations can lead to measures to protect patients from fungal infections. The literature on this topic contains insufficient and sometimes ambiguous information. This is evidenced by the fact that there are no international recommendations or guidelines defining the methodology of air sampling and the interpretation of the results obtained. Surgical departments, intensive care units and medical mycology laboratories are, therefore, left to their own devices, leading to significant differences in the implementation of mycological surveillance in hospitals. The aim of this mini-review is to provide an overview of the current methods of air sampling and interpretation of results used in medical mycology laboratories.

Sustainability in the Breast Operating Theatre: Promoting a Multidisciplinary Sustainability strategy across multiple centres

Operating theatres in hospitals are critical areas that generate a significant amount of waste, including single-use items such as disposable hats which has a significant effect on our NHS carbon footprint. The use of appropriate surgical attire, including hats, plays a vital role in maintaining hygiene and promoting a sterile environment within operating theatres. The introduction of the RCS surgical green checklist has highlighted several ways to improve sustainability in a theatre setting.

Improving compliance with personal protective equipment among anaesthetists through behaviour-changing interventions during the coronavirus disease 2019(COVID-19) pandemic.

Since 2020, the coronavirus disease 2019 (COVID-19) pandemic has seen many changes in our daily infection prevention behaviours so as to reduce healthcare-associated transmission of COVID-19 in patients and healthcare workers. In the early phases of the COVID-19 pandemic of 2020, there was much emphasis on compliant personal protective equipment utilization in the operating theatres (OTs) for COVID-19-positive patients. However, during this period, there was a lack of international validated protocols on the appropriate handling and subsequent storage of personal protective equipment in the context of aerosol-generating procedures in OTs for asymptomatic antigen rapid test (ART)-negative patients. Given the potential for transmission even with a negative ART due to the incubation period, our team developed a checklist of eye protection (e.g. goggles/face shield) and N95 mask handling and storage in non-isolation OTs for these patients. We sought to improve the compliance of best practices from 20% to 80% amongst junior anaesthetists in Singapore General Hospital so as to prevent infection transmission and cross-contamination in the OT through education and behaviour-changing interventions. This quality improvement project took place over 19 weeks from June to October 2020 by our team of anaesthetists and nurse clinicians in the non-isolation OT setting. To analyse the problem, we performed a root cause analysis to understand attitudes and beliefs driving their behaviour. The top 80% of cited root causes for non-compliance then guided prioritization of resources for subsequent behaviour-changing interventions. Using the comprehensive infection control checklist, we conducted several plan-do-study-act cycles while implementing this new checklist amongst junior anaesthetists. A total of 227 assessments of junior anaesthetists were made in the care of asymptomatic ART-negative patients. Compliance with correctly handling goggles post-intubation started out as 33.3% in Week 1, which improved to 78.5% by Week 19. Compliance with goggle storage and face shield disposal started out at 13.6% in Week 1 and increased to 78.6% by Week 19. We attributed this improvement to education and behaviour-changing interventions. This quality improvement project focusing on improving compliance with personal protective equipment utilization during the COVID-19 pandemic in the management of asymptomatic ART-negative patients in non-isolation OTs demonstrated the importance of interventions of education, persuasion, modelling, and training in effecting and sustaining organizational behaviour change in physicians and other healthcare personnel.

Training Performance Assessment for Intracranial Aneurysm Clipping Surgery Using a Patient-Specific Mixed-Reality Simulator: A Learning Curve Study.

The value of simulation-based training in medicine and surgery has been widely demonstrated. This study investigates the introduction and use of a new mixed-reality neurosurgical simulator in aneurysm clipping surgery, focusing on the learning curve and performance improvement. Five true-scale craniotomy head models replicating patient-specific neuroanatomy, along with a mixed-reality simulator, a neurosurgical microscope, and a set of microsurgical instruments and clips, were used in the operation theater to simulate aneurysm microsurgery. Six neurosurgical residents participated in five video-recorded simulation sessions over 4 months. Complementary learning modalities were implemented between sessions. Thereafter, three blinded analysts reported on residents' use of the microscope, quality of manipulation, aneurysm occlusion, clipping techniques, and aneurysm rupture. Data were also captured regarding training time and clipping attempts. Over the course of training, clipping time and number of clipping attempts decreased significantly (P = .018, P = .032) and the microscopic skills improved (P = .027). Quality of manipulation and aneurysm occlusion scoring improved initially although the trend was interrupted because the spacing between sessions increased. Significant differences in clipping time and attempts were observed between the most and least challenging patient models (P = .005, P = .0125). The least challenging models presented higher rates of occlusion based on indocyanine green angiography evaluation from the simulator. The intracranial aneurysm clipping learning curve can be improved by implementing a new mixed-reality simulator in dedicated training programs. The simulator and the models enable comprehensive training under the guidance of a mentor.

Effectiveness of Postoperative Analgesia with Rectal Placement of Diclofenac Sodium in Patients Undergoing Gynecological and Obstetrical Surgeries under General Anesthesia

Objective: To determine the frequency of need for postoperative intravenous analgesia after rectal diclofenac suppository in patients undergoing lower abdominal gynecological or obstetrical surgery under general anesthesiaStudy Design: Cross-sectional study.Place and Duration of Study: The study was carried out at the Operation Theater and Postoperative Ward of Sheikh Zayed Hospital, Lahore, Pakistan from January 2021 to July 2021.Methods: A total of 245 women undergoing gynecological and obstetrical surgeries under general anesthesia were enrolled in the study using non-probability consecutive sampling. All the participants were recruited after obtaining informed consent and meeting the inclusion criteria. All subjects had a single 100mg diclofenac suppository inserted rectally after undergoing general anesthesia, and their Visual Analog Scale (VAS) scores for postoperative analgesia were recorded immediately after surgery and again at 1, 6, and 24 hours.Results: The mean age of the patients was 37 years, with a standard deviation of 6.2. The mean VAS (Visual Analog Scale) scores at 1, 6, 12, and 24 hours were 3 (±1.24), 5 (±1.46), 7 (±1.93), and 6 (±2.14), respectively. The need for rescue analgesia was reported in 15.9% of cases at 1 hour, 37.1% at 6 hours, 82% at 12 hours, and 68.2% at 24 hours.Conclusion: The administration of diclofenac via rectal placement led to a notable decrease in Visual Analog Scale scores and a lower incidence of needing additional pain relief within the first 6 hours after surgery.

A Rare Case of Perioperative Methemoglobinemia in a Paediatric Child: A Case Report

Methemoglobinemia is a rare condition that caused impairment of oxygen delivery manifested as spectrum of features ranging from mild desaturations to severe cyanosis and even death. It is rarely seen in the operative theatre and its incidence is scarcely reported. Even low risk patients are susceptible despite having no significant exposure to commonly reported precipitating oxidizing agents. We described a case of perioperative methemoglobinemia in a 10-year-old child, which was planned for foreign body removal in left ear. The operation went successfully; however, the child developed desaturation postoperatively. Arterial blood gas was measured, and methemoglobin levels were noticeably high at 27.1%. The child remained hemodynamically stable, monitored conservatively, and was successfully treated with intravenous methylene blue. We postulated that the cause of methemoglobinemia was intravenous fentanyl usage, as other oxidising agents were excluded. Clinicians must be aware of the possibility of perioperative methemoglobinemia causing unanticipated desaturations and unexplained cyanosis.

Place of urolithiasis in the spectrum of urological pathologies, practices and use of endourological procedures in the management of calculi of the upper urinary tract: results of a survey of referral centres in Africa.

Our aim was to determine the current trend of endourology in the management of upper urinary tract calculi in Africa reference centres. We conducted an online multiple-choice questionnaire survey involving 46 centres from 27 countries using a structured well-designed Google Form (®) questionnaire. The questionnaires were distributed to the head of service through their emails. The questions collected demographic data about the centre, the epidemiology of urolithiasis, diagnostic means and management of upper urolithiasis, especially access to endourology procedures and their practices. Descriptive analyses were performed. The participation rate was 77.9%. Urinary lithiasis was one of the three main pathologies encountered in 42/46 centres. 33 centres had easy access to CT scanners and 34 had operating theatres equipped with endo-urological surgery equipment. Of these 34 centres, 30 perform endourology for the management of upper urinary tract stones. Rigid ureteroscopy is the main technique used by the centres. It is the only endourology technique used for stone management by 12 centres (40%). 7/30 (23.3%) have the option of performing rigid ureteroscopy, flexible ureteroscopy and percutaneous nephrolithotomy. The frequency of procedures varies widely, with 43.3% rarely performing endourological surgery. Seventeen centres have their operating theatre equipped with a fluoroscope and 6/42 centres have extracorporeal lithotripsy. Open surgery is still used in 29/42 centres (69.1%). Laparoscopy is available in 50% of centres, but none reported performing laparoscopic lithotomy. In Africa, urinary lithiasis plays an important role in the activities of referral centres. Modern management techniques are used to varying degrees (not all centres have them) and with very variable frequency. Open surgery is still widely performed as a management. Rigid ureteroscopy is the main endourological technique. It is essential to develop the practice of modern urology in Africa, mainly endourology.

Organization of the emergency operating room

The structure and organization of operating theatres vary from one healthcare facility to another. Some establishments have a multi-disciplinary operating theatre, with shared operating theatres and staff, while others have separate operating theatres, often divided by discipline. Emergencies are therefore dealt with in the operating theatres for scheduled surgery. However, some university hospitals also have emergency operating theatres.

Broad Responses and Attitudes to Having Music in Surgery (The BRAHMS Study): An Australia and Aotearoa New Zealand Perspective

BackgroundSurgery is a stressful exercise, and the experience of occupational stress may have impacts on surgical performance, and surgeon well-being. Music is played in operating theatres (OTs) throughout the world, and while it may improve surgical performance, and reduce clinician stress within the OT, concerns exist over its distracting and noise-creating properties. MethodsIn this prospective observational study, between May to August 2022, Vascular, General and Paediatric surgeons and registrars in Australia and Aotearoa New Zealand (AoNZ) responded to a survey investigating the way they use music, and their perceptions and attitudes towards its effect on the OT environment. Binomial logistic regression and Chi squared tests of association were performed, accepting p < 0.05 as significant. ResultsIn this cohort of 120 surgeons, 45 % were vascular specialists, 30 % were female and 59 % were consultant surgeons. The most commonly preferred music genres were easy listening and pop. Over 75 % of surgeons enjoyed having music in their OTs with the majority reporting it improved their temperament, how mentally fatiguing a procedure felt and how anxious or stressed they felt. Vascular surgeons were more likely to believe music had a positive influence on communication than their general and paediatric surgery colleagues (p < 0.01). Registrars had significantly higher odds of believing music had a positive effect on their temperament, and how stressed and anxious they felt when operating, when compared to consultants (p < 0.05). ConclusionsThis study provides a window into the surgeons' use of and attitudes towards intra-operative background music and its effect on stress and cognitive load in Australia and AoNZ. While overall, music is viewed positively by this cohort, there was some difference seen across specialties and level of experience. Further subjective and objective data in this field may provide useful information to guide hospital policy and inform pathways for clinician wellbeing.

Knowledge, Attitude And Practice Of Nurses Regarding Infection Control In Operation Theater In Secondary Care Hospital

Knowledge, Attitude And Practice Of Nurses Regarding Infection Control In Operation Theater In Secondary Care Hospital

Nitrous oxide splurge in a tertiary health care center and its environmental impact: No more laughing stock.

Nitrous oxide has been an integral part of surgical anesthesia for many years in the developed world and is still used in developing countries such as India. The other main concerns in low-resource countries are the lack of an advanced anesthesia gas-scavenging system and modular surgical theatres. As a greenhouse gas that has been present in the atmosphere for more than 100 years and damages the ozone layer, nitrous oxide is three times worse than sevoflurane. Here, we conducted an observational study to quantify the annual nitrous oxide consumption and its environmental impact in terms of carbon dioxide equivalence in one of busiest tertiary health care and research centers in Northern India. Data related to nitrous oxide expenditure' from the operation theatre and manifold complex of our tertiary care hospital and research center from 2018 to 2021 were collected monthly and analyzed. The outcomes were extracted from our observational study, which was approved by our institutional ethics board (INT/IEC/2017/1372 Dated 25.11.2017) and registered prospectively under the Central Registry (CTRI/2018/07/014745 Dated 05.07.2018). The annual nitrous oxide consumption in our tertiary care hospital was 22,081.00, 22,904.00, 17,456.00, and 18,392.00 m3 (cubic meters) in 2018, 2019, 2020, and 2021, respectively. This indicates that the environmental impact of nitrous oxide (in terms of CO2 equivalents) from our hospital in 2018, 2019, 2020, and 2021 was 13,016.64, 13,287.82, 10,289.94, and 10,841.24 tons, respectively. This huge amount of nitrous oxide splurge is no longer a matter of laughter, and serious efforts should be made at every central and peripheral health center level to reduce it.

Synthetic solutions for re‐growing human corneas

Cornea blindness is still treated mainly by corneal transplantation, using donated allograft human corneas. However, a severe global shortfall leaves an estimated 12.7 million patients on waiting lists despite methods of using one cornea for two different partial‐thickness grafts. Even more individuals are not on waiting lists because they have no access to transplantation in their countries or regions. However, even if donor tissues were readily available, patients with inflamed, severely damaged corneas are at high risk of rejecting conventional transplantation. Various solutions have been proposed as alternatives to corneal allografting, including the development of keratoprostheses and stem cell grafting. We posited using cell‐free implants that mimic the extracellular matrix of the human cornea to recapitulate the environment during corneal development and stimulate the endogenous cells within the patient's eyes to affect regeneration. We used cell‐free corneal implants made from chemically crosslinked recombinant human collagen to promote in situ tissue regeneration in pathologic corneas, including high‐risk ones. We successfully developed and tested recombinant human solid collagen‐based implants that promoted stable regeneration in inflamed human patient corneas based on phosphorylcholine (MPC). However, solid corneas require a full operating theatre and staffing, which is costly and not accessible to more remote regions in Canada and globally. Burns and severe infections that can lead to perforations are medical emergencies that require immediate methods to seal the eye. In many centres, cyanoacrylate glue is used as a sealant, but this is toxic and kills surrounding cells, often necessitating follow‐on transplantation. We developed a synthetic, biocompatible, and adhesive liquid hydrogel (LiQD Cornea), which would replace these toxic cyanoacrylate glues. LiQD cornea is applied as a liquid but quickly adheres and gels within corneal tissue defects like a dental filling. It can be used to fill ulcers and other damaged areas. Then its similarity at a molecular level to a natural tissue framework promotes tissue regeneration, treating corneal perforations effectively without transplantation. Further, due to the synthetic nature of the material, risks associated with disease transmission are reduced compared to natural products. We see LiQD Cornea potentially used in outpatient clinics instead of operating theatres, maximizing practicality and minimizing health care costs.

A comparative study of key quality performance indicators in anesthesia and surgery in operation theatre at a tertiary care hospital in Rishikesh.

A Key Performance Indicator (KPI) is a critical metric measuring organizational success or specific activities, reflecting the periodic achievement of operational goals aligned with strategic objectives. A retrospective cross-sectional study of key quality performance indicators, (CQI-NABH) concerning anesthesia and surgical services was conducted at a tertiary care hospital after taking institutional ethical clearance (AIIMS/IEC/21/150). It was as per COP 13, COP 14, and COP 15 standards of NABH 4th edition published in 2015. The study was conducted at the department of anesthesiology at a tertiary care hospital, and data were retrospectively analyzed from 01 October 2019, till November 2020. All patients undergoing elective or emergency surgical procedures under monitored anesthesia care and regional or general anesthesia during the study period were considered.The primary objective was to analyze Continuous Quality Improvement (CQI) in perioperative services, with secondary goals including gap identification, suggesting corrective actions, and examining quality indicators during the COVID-19 pandemic in 2020. Out of 8574 patients operated during the study, 6705 were in the four months before the pandemic, and 1869 were operated during the COVID-19 scenario. In the pre-COVID era, many of the cases were performed on an elective basis (71.23%), and emergencies constituted 16.9% of the total number of cases. In the COVID era, most of the cases were emergencies (45.4%) and semi-emergencies (40.25%), and elective cases were only 14.05% of the total cases performed. The percentage of modification of anaesthesia plans ranged from 0-3.34%. Adverse anaesthesia events were observed in 0-2.1%, primarily related to cardiovascular, respiratory, and airway issues. No anaesthesia-related mortality was reported. Prophylactic antibiotic administration within one hour of surgery ranged from 88-100%. Monitoring and evaluating healthcare performance, specifically through KPIs, is vital for optimizing care and resource utilization. These indicators provide an overview of hospital service efficiency, aiding in key areas such as patient treatment, satisfaction, healthcare quality improvement, cost reduction, and optimal resource utilization. Addressing identified issues ensures effective and sustainable quality improvement in anaesthesia services, emphasizing ongoing monitoring as a foundation for hospital quality assurance.

Prevention of Pressure Sore Using Silicone Gel Pad in Prolonged Surgery

Pressure ulcers develop primarily from friction and shear and are progressive. It is usually found in bedridden and immobile people. Spinal cord injury patients have loss of sensation which adds to the problem. Patients with stroke, who have undergone long surgery, long bone fracture, not able to move tend to develop a pressure sore. Pressure ulcers are preventable usually and their management depends on their severity. This article discusses the prevention of pressure sore by using silicone gel pad in operation theatre that is undergoing prolonged surgery

Effects of Magnesium Sulphate, Dexmedetomidine and Lignocaine on Perioperative Haemodynamic and Postoperative Analgesia in Patients Undergoing Laparoscopic Abdominal Surgeries: A Randomised Clinical Study

Introduction: Laparoscopic surgeries currently represent the mainstay of surgical modalities. Pneumoperitoneum imposes significant intraoperative haemodynamic alterations, which are more pronounced in elderly patients and those with co-morbid conditions. Inadequate pain relief in the perioperative period may result in various physiological and psychological traumas. Aim: To investigate the effects of magnesium sulphate, dexmedetomidine, and lignocaine on the haemodynamic responses and postoperative analgesia in patients undergoing laparoscopic abdominal surgeries. Materials and Methods: This double-blinded, randomised clinical study was conducted in the general surgery operation theatre, Post-anaesthetic Care Unit (PACU), and the male and female surgery ward of RG Kar Medical College and Hospital, Kolkata, West Bengal, India from March 1, 2021, to March 1, 2022. The study involved 105 subjects assigned to Group-L, who received an injection of lignocaine as a loading dose of 1.5 mg/kg intravenously over 2-4 minutes before induction, followed by a continuous infusion of 2 mg/kg/hour throughout the surgery. Group-M received a loading dose of MgSO4 at 30 mg/ kg over 15 minutes before induction, followed by 15 mg/kg/hour throughout the surgery, and Group-D received a loading dose of dexmedetomidine at 1 mcg/kg over 10 minutes before induction, followed by a continuous infusion of 0.5 mcg/kg/min throughout the surgery. Data on Heart Rate (HR), Mean Arterial Pressure (MAP), and the total dose of rescue analgesic administered in the postoperative 24 hours were recorded and analysed using Analysis of Variance (ANOVA) and Tukey’s Honestly Significant Difference (HSD) test, as well as the Chi-square test where applicable. A p-value of less than 0.05 was considered statistically significant. Results: The groups were comparable in terms of demographic variables and baseline haemodynamic status. The average age in Group-D was 39.13±9.48 years, in Group-M was 37.30±8.14 years, and in Group-L was 36.5±7.2 years (p=0.26). Group-D had 60% males, Group-M had 57% males, and Group-L had 60% males. The mean Body Mass Index (BMI) of Group-D was 25.9±2.03 (kg/m2 ), Group-L (Lignocaine) was 24.7±2.7, and Group-M (Magnesium Sulphate) was 23.8±3.2. Dexmedetomidine was found to be superior in maintaining haemodynamic stability throughout the perioperative period (Preinduction HR: Group-D=79.43, Group-L=79.06, Group-M=82.09; Postinduction HR: Group-D=86.49, Group-M=65.91, GroupL=72.69). There was a significant decrease in postintubation MAP, most pronounced in the Magnesium Sulphate and Dexmedetomidine groups. Post-pneumoperitoneum, the surge in MAP was most effectively prevented by Dexmedetomidine. The lowest amount of rescue analgesic (injection Diclofenac in mg) was used in the Dexmedetomidine group (55.86±5.05), followed by the Lignocaine group (126.43±17.69). Patients in the Magnesium group required the highest amount of rescue analgesic (156.43±7.91). The number of patients receiving rescue analgesia was significantly higher in the Lignocaine and Magnesium Sulphate groups (Group-D: 6.5±3.14565, Group-L: 14.75±7.36, Group-M: 18.25±8.057). Conclusion: Dexmedetomidine was more effective in maintaining haemodynamic stability throughout the perioperative period and exhibited superior postoperative analgesic properties. Magnesium Sulphate and lignocaine were more effective in preventing postintubation surges.
