Understanding patient and family experiences of critical care in Bangladesh and India: What are the priority actions to promote person-centred care?

Patients' experiences in the intensive care unit (ICU) can enhance or impair their subsequent recovery. Improving patient and family experiences on the ICU is an important part of providing high quality care. There is little evidence to guide how to do this in a South Asian critical care context. This study addresses this gap by exploring the experiences of critically ill patients and their families in ICUs in Bangladesh and India. We elicit suggestions for improvements from patients, families and staff and highlight examples of practices that support person-centred care. This multi-site hospital ethnography was carried out in five ICUs in government hospitals in Bangladesh and India, selected using purposive sampling. Qualitative data were collected using non-participant observation and semi-structured interviews and analysed using reflexive thematic analysis. A total of 108 interviews were conducted with patients, families, and ICU staff. Over 1000 hours of observation were carried out across the five study sites. We identified important mediators of patient and family experience that span many different aspects of care. Factors that promote person-centred care include access to ICU for families, support for family involvement in care delivery, clear communication with patients and families, good symptom management for patients, support for rehabilitation, and measures to address the physical, environmental and financial needs of the family. This study has generated a list of recommendations that can be used by policy makers and practitioners who wish to implement person-centred principles in the ICU.

Recent advances in paediatric anaesthesia.

Recent development in science has led to a significant improvement in safety for the anaesthetic management of children. Enhanced recovery after surgery is one of the novel approaches aiming to enhance paediatric surgical outcomes and their quick recovery. Preoperative counselling, minimal fasting, and no routine pharmacological premedication are critical components of enhanced recovery after surgery. As anaesthetists, management of airway is our priority and introduction of paraoxygenation in addition to preoxygenation has resulted in reduction in desaturation episodes during periods of apnoea. Safe care has been made possible by improvements in monitoring, equipment, medications, techniques, and resuscitation protocols. We are motivated to collect more evidence regarding ongoing disputes and issues, such as the effect of anaesthesia on neurodevelopment.

Electrocoagulation followed by sound agitation for removal of nitrogen and carbon-based pollutants from industrial wastewater.

The herculean imprecation of nitrogen-based pollutant like ammoniacal nitrogen (AN) and chemical oxygen demand (COD) on aquatic milieu is now a concern for the dye, pharma and fertiliser industries. Wastewater from these is characterised with high concentration of AN, COD and total dissolved solids (TDS), treatment of which is of utmost importance for a cleaner environment. In the current research work, an attempt was made to apply integrated electro-coagulation (EC) - sonication process for the removal of COD and AN from highly acidic dye intermediate wastewater containing high to very high concentration of COD and AN. Systematic laboratory experiments were conducted for the treatment of dye intermediate wastewater and influences of pH (5-11), applied voltage (0.5-4V) and electrolysis time (30-120 min) were investigated. A Response Surface Methodology (RSM) was used for optimization of major operating parameters for EC. The conditions for minimum fraction remaining (C/C0), was found to be same for both COD and AN, i.e. pH 7, time 90 min and applied voltage 2V. The C/Co value for COD and AN were 0.244 and 0.302, respectively. The C/Co value of COD and AN in combined EC-Sonication process with optimum operating conditions were 0.145 and 0.228 respectively with sonication time 60 min at a frequency of 33 kHz. Thus, EC - sonication process is an efficacious process for their removal from dye industrial wastewater.

Effects of fentanyl and dexmedetomidine as adjuvants to bupivacaine in paravertebral block for postoperative analgesia in patients undergoing modified radical mastectomy: A prospective randomised double-blind study.

Background and Aims: Paravertebral block (PVB) is an established method, indicated for postoperative analgesia after modified radical mastectomy (MRM). Although many additives to bupivacaine in PVB have been tried to prolong the analgesia in postoperative period, no additive has been found without any adverse effects. We have compared the duration of analgesia in PVB using adjuvants like dexmedetomidine and fentanyl with bupivacaine after MRM. Methods: A total of 60 female patients enroled for MRM were divided into two groups of 30 patients each. Group BF received PVB with 20 ml bupivacaine 0.25% with fentanyl 1 mg/kg and group BD received 20 ml bupivacaine 0.25% with dexmedetomidine 1 mg/kg for PVB. After confirming successful PVB, surgery was done under general anaesthesia. Time for first rescue analgesic request was the primary outcome of the study. The secondary outcome was comparison of visual analogue scale scores for pain and total analgesic consumption. Side effects like sedation, nausea, vomiting, bradycardia and hypotension in the postoperative period till 24 h were also assessed. Results: The time for first rescue analgesic request was 6.32 ± 1.75 h in the BD group contrary to 3.94 ± 2.12 h in group BF (P < 0.05). Total paracetamol consumed as rescue analgesia in the first 24 h of postoperative period was remarkably reduced in group BD (1.7 ± 0.94 gm) in contrary to group BF (2.6 ± 0.98 gm) (P < 0.05). There was no significant difference in the incidence of complications between the groups. Conclusion: Dexmedetomidine provides prolonged postoperative analgesia compared with fentanyl when used as an adjuvant to bupivacaine in PVB after MRM.

Electro-Fenton assisted sonication for removal of ammoniacal nitrogen and organic matter from dye intermediate industrial wastewater.

The intricacy in the treatment of effluents from the textile sector attracts the researchers since 20th century. Dye intermediate manufacturing industries are responsible for producing the toxic pollutants such as nitro-aromatics, benzene, toluene, phenol, heavy metals etc. with intense colour. The present study focuses on the performance of combined Electro-Fenton (EF) and sonication for the removal of ammoniacal nitrogen and COD from dye intermediate manufacturing wastewater. Batch experiments of EF were performed using graphite electrodes and sonication was applied to the EF treated wastewater to enhance the treatment performance. A number of experiments were executed to discover the influence of pH, applied voltage, Fenton catalyst dosage and time of electrolysis on the removal efficiency of EF batch process was scrutinized. The pH was varied between 2 and 4, applied voltage from 1 to 4V, Fenton catalyst dosage between 50 and 200 mg L-1 and time between 15 and 180 min. At optimum condition i.e. pH 3, applied voltage 3V, Fenton catalyst dosage of 100 mg L-1and 120 min electrolysis time, the percentage removal obtained for ammoniacal nitrogen and COD were 59.4% and 79.2% respectively. The removal efficiency was increased to 65.5% for ammoniacal nitrogen and 85.4% for COD after applying sonication to the EF treated wastewater. The removal of ammoniacal nitrogen and COD can be achieved in a scientific and feasible way by combining EF process with sonication.

Post-operative analgesia for shoulder arthroscopic surgeries: A comparison between inter-scalene block and shoulder block.

BACKGROUND AND AIMS: Shoulder arthroscopic surgeries can produce intense post-operative pain. Inter-scalene block (ISB) provides good analgesia after shoulder surgery, but concerns over its associated risks have prompted the search for alternatives. Shoulder block (SHB), which includes suprascapular block along with axillary nerve (AN) block, was recently proposed as an alternative to ISB, but evidence of its efficacy is conflicting. The aim of our study was to compare SHB with ISB in shoulder surgery for post-operative analgesia. METHODS: A total of 76 patients scheduled for shoulder arthroscopic surgery were equally divided into 2 groups of 38 patients each: ISB group and SHB group. Both the nerve blocks were achieved by using ultrasound and a nerve stimulator. Visual analogue scale (VAS) scores were evaluated at 1, 4, 6, 12 and 24 h post-operatively. The time to first analgesia request, total analgesic requirement for 24 h post-operatively, patient satisfaction and any complications were recorded. RESULTS: SHB provided equivalent analgesia to ISB in terms of post-operative VAS scores. Time to first analgesic request was 6.2 ± 1.3 h in ISB group and 5.9 ± 1.2 h in SHB group, which was not statistically significant. Complications like subjective dyspnoea and weakness of arm were significantly higher in ISB group compared to SHB group. Patient satisfaction scores were also significantly higher in SHB group compared to ISB group. CONCLUSION: SHB is as effective as ISB for post-operative pain relief and with fewer complications due to selective blockade of suprascapular and axillary nerves.

Comparison of pregabalin with gabapentin as preemptive analgesic in lumbar spine surgery.

BACKGROUND AND AIMS: Analgesic effect of gabapentin and pregabalin is well-defined in the treatment of neuropathic pain. Postoperative pain after lumbar spine surgery limits the function of patients in the postoperative period, for which the search for ideal analgesic goes on. The aim of the present study was to compare pregabalin and gabapentin as a pre-emptive analgesic in elective lumbar spine surgeries. MATERIAL AND METHODS: In this randomized prospective study, 75 patients were allocated into three groups of 25 each. Group G, group PG, and group P received two capsules of gabapentin 300 mg each, two capsules of pregabalin 150 mg each, and two multivitamin capsules, respectively, with sip of water 1 hour before the expected time of induction of anesthesia. Time for requirement of first dose of rescue analgesia, reduction in postoperative pain score and total dose of rescue analgesic used in first 24 hours postoperatively, and side effects were compared. RESULT: Time for requirement of first dose of rescue analgesic in PG group was 180.12 min and in G group was 104.16 min, which was statistically significant. Both G and PG group had lower visual analogue scale (VAS) score in comparison to P group, which was statistically significant. Consumption of rescue analgesic was less in G and PG group in comparison to P group. Amount of rescue analgesic requirement were low in PG group in comparison to G group (P < 0.001). CONCLUSION: Though both study drugs had produced prolonged postoperative analgesia compared to placebo, pregabalin had better analgesic profile in postoperative period than gabapentin.

A clinical comparison between 0.5% levobupivacaine and 0.5% levobupivacaine with dexamethasone 8 mg combination in brachial plexus block by the supraclavicular approach.

BACKGROUND AND AIMS: Dexamethasone as an adjuvant to bupivacaine for supraclavicular brachial plexus (SCBP) block prolongs motor and sensory blockade. However, the effect of dexamethasone (8 mg) when added to levobupivacaine has not been well studied. This study was conducted to find out analgesic efficacy of dexamethasone as adjuvant to levobupivacaine in SCBP block. METHODS: Ultrasound- guided SCBP block was given to sixty patients, randomly assigned into two groups. Group S (thirty patients) received 2 mL normal saline with 25 mL levobupivacaine (0.5%) and Group D (thirty patients) received 2 mL of dexamethasone (8 mg) with 25 mL of levobupivacaine (0.5%), respectively. Time for the first rescue analgesia, number of rescue analgesics required in 24 h and different block characteristics was assessed. Chi-square test and Student's t-test were used for statistical analysis. RESULTS: Time for request of the first rescue analgesia was 396.13 ± 109.42 min in Group S and 705.80 ± 121.46 min in Group D (P < 0.001). The requirement for rescue analgesics was more in Group S when compared to Group D. The onset of sensory and motor block was faster in Group D when compared to Group S. The mean duration of sensory and motor block was significantly longer in Group D than Group S. CONCLUSION: The addition of dexamethasone to levobupivacaine in SCBP blockade prolonged time for first rescue analgesia and reduced the requirement of rescue analgesics with faster onset and prolonged duration of sensory and motor block.

Sedation in oral and maxillofacial day care surgery: A comparative study between intravenous dexmedetomidine and midazolam.

INTRODUCTION: Sedation is an important component of day care oral and maxillofacial surgical procedures under local anesthesia. Although various sedative drugs in different regimens have been used for sedation, an ideal agent and regimen are yet to be established. AIM: The aim of this study is to compare the efficacy of intravenous (IV) dexmedetomidine and midazolam as a sedative agent for day care oral and maxillofacial surgical procedures. SETTINGS: The study was conducted in the Department of Oral and Maxillofacial Surgery, SCB Dental College and Hospital, Cuttack, Odisha, India. MATERIALS AND METHODS: A total of sixty adult patients of age group 18-65 years, of either sex were randomly selected equally in two groups for the study. One group named Group D received dexmedetomidine and the other named Group M received midazolam. Patients were evaluated for oxygen saturation (SPO2), respiration rate (RR), systolic blood pressure (SBP), diastolic blood pressure (DBP), Ramsay sedation score, bispectral index (BIS) score, amnesia, Aldrete score, relaxation during the surgery, and drug preference. RESULTS: Midazolam was associated with greater amnesia. Dexmedetomidine was associated with lower heart rate, SBP, and DBP. There was no significant difference in SPO2, RR, Aldrete score, Ramsay sedation score, and BIS score between the two drugs. Patient preference and relaxation were more in dexmedetomidine group. CONCLUSION: IV dexmedetomidine is a comparable alternative to midazolam for sedation in day care oral and maxillofacial surgery under local anesthesia. It is the preferred drug when a lower heart rate and blood pressure or less amnesia is needed without any serious side effects.

Reversal agents in anaesthesia and critical care.

Despite the advent of short and ultra-short acting drugs, an in-depth knowledge of the reversal agents used is a necessity for any anaesthesiologist. Reversal agents are defined as any drug used to reverse the effects of anaesthetics, narcotics or potentially toxic agents. The controversy on the routine reversal of neuromuscular blockade still exists. The advent of newer reversal agents like sugammadex have made the use of steroidal neuromuscular blockers like rocuronium feasible in rapid sequence induction situations. We made a review of the older reversal agents and those still under investigation for drugs that are regularly used in our anaesthesia practice.

Eisenmenger's syndrome in pregnancy: Use of epidural anesthesia and analgesia for elective cesarean section.

We describe a case of a pregnant patient with a large ventricular septal defect (VSD) and pulmonary artery hypertension, presented to the hospital and underwent elective cesarean section under epidural anesthesia and postoperative analgesia. The procedure was uneventful till the patient was discharged on 10(th) day.

Bilateral transversus abdominis plane block as a sole anesthetic technique in emergency surgery for perforative peritonitis in a high risk patient.

Although transversus abdominis plane (TAP) block is an effective way of providing analgesia in post-operative abdominal surgery patients; however, it can be considered as an anesthetic technique in high-risk cases for surgery. We report a case of a geriatric female with chronic obstructive pulmonary disease in the respiratory failure, hypotension, posted in an emergency with old perforation leading to peritonitis. The surgery was successfully conducted under bilateral TAP block, which was used as a sole anesthetic technique. TAP block can be considered as an anesthetic technique for abdominal surgery in moribund patients.

Anaesthetic consideration for neonatal surgical emergencies.

A newborn requires constant vigilance, rapid recognition of the events and swift intervention during anaesthesia. The anaesthetic considerations in neonatal surgical emergencies are based on the physiological immaturity of various body systems, poor tolerance of the anaesthetic drugs, associated congenital disorders and considerations regarding the use of high concentration of oxygen. The main goal is for titration of anaesthetics to desired effects, while carefully monitoring of the cardiorespiratory status. The use of regional anaesthesia has shown to be safe and effective. Advancements in neonatology have resulted in the improvement of the survival of the premature and critically ill newborn babies. Most of the disorders previously considered as neonatal surgical emergencies in the past no longer require immediate surgery due to new technology and new methods of treating sick neonates. This article describes the common neonatal surgical emergencies and focuses on factors that affect the anaesthetic management of patients with these disorders.

Diabetic parturient - Anaesthetic implications.

Pregnancy induces progressive changes in maternal carbohydrate metabolism. As pregnancy advances insulin resistance and diabetogenic stress due to placental hormones necessitate compensatory increase in insulin secretion. When this compensation is inadequate gestational diabetes develops. 'Gestational diabetes mellitus' (GDM) is defined as carbohydrate intolerance with onset or recognition during pregnancy. Women diagnosed to have GDM are at increased risk of future diabetes predominantly type 2 DM as are their children. Thus GDM offers an important opportunity for the development, testing and implementation of clinical strategies for diabetes prevention. Timely action taken now in screening all pregnant women for glucose intolerance, achieving euglycaemia in them and ensuring adequate nutrition may prevent in all probability, the vicious cycle of transmitting glucose intolerance from one generation to another. Given that diabetic mothers have proportionately larger babies it is likely that vaginal delivery will be more difficult than in the normal population, with a higher rate of instrumentally assisted delivery, episiotomy and conversion to urgent caesarean section. So an indwelling epidural catheter is a better choice for labour analgesia as well to use, should a caesarean delivery become necessary. Diabetes in pregnancy has potential serious adverse effects for both the mother and the neonate. Standardized multidisciplinary care including anaesthetists should be carried out obsessively throughout pregnancy. Diabetes is the most common endocrine disorder of pregnancy. In pregnancy, it has considerable cost and care demands and is associated with increased risks to the health of the mother and the outcome of the pregnancy. However, with careful and appropriate screening, multidisciplinary management and a motivated patient these risks can be minimized.

Regional & topical anaesthesia of upper airways.

SUMMARY: A combination of techniques are required to adequately anaesthetise upper airway structures for awake intubation. The widest coverage is provided by the inhalational technique. This technique, however, does not always provide a dense enough level of anaesthesia for all patients. Supplementation of this technique with any of the specific nerve blocks is an excellent way to accomplish efficacious anaesthesia for awake inubation. Anaesthetising upper airway is not a difficult skill to master and should be in the armamentarium of all practising anaesthetist.
