DNA profiling of sugarcane genotypes using randomly amplified polymorphic DNA

DNA profiles of 40 sugarcane genotypes were constructed with 30 RAPD markers. Sugarcane genotypes of both Saccharum officinarum and S. barberi were included in this study. Multiple alleles were detected from each RAPD; there was a high level of polymorphism. On average, 7.93 alleles were produced per primer, giving a total of 238 alleles. The genetic distances between these genotypes were assessed with the POPGENE DNA sequence analysis software. A dendrogram was constructed from these data; cultivated species of sugarcane formed clusters with S. barberi genotypes. The 40 genotypes were clustered into two main groups; genetic distances ranged from 20.29 to 64.66%. These RAPD fingerprints will help sugarcane breeders to evaluate the efficiency of current conventional breeding methods and will help characterize the genetic pedigree of commercial sugarcane varieties. These data will also be valuable for conservation and utilization of the genetic resources in germplasm collections.

Genetic diversity of Saccharum officinarum accessions in Pakistan as revealed by random amplified polymorphic DNA

Genetic diversity of 20 sugarcane accessions in Pakistan was studied using 21 random amplified polymorphic DNA markers. The mean genetic distance between the cultivars was 39.03%, demonstrating that a large part of the genome is similar among the accessions. This probably arises from a lack of parental diversity, with few clones, which are themselves related, contributing to the parentage of these varieties. Among the varieties, none was found to be totally distinct and divergent from the others. We conclude that the current Pakistan commercial varieties have a limited genetic base and that there is a need to diversify commercial sugarcane lines in Pakistan by introducing new germplasm sources.

Lead-induced oxidative stress adversely affects health of the occupational workers

Lead is a persistent toxic metal and associated with impairment of various body functions in occupational workers. The main objective was to determine the lead-induced oxidative stress and adverse health effects by biochemical markers in industrial workers. One hundred and forty-eight males consisting of 87 lead-exposed industrial workers and 61 controls were included. Blood lead level (BLL) was determined on a 3010B ESA lead analyzer. Blood complete counts were done on a hematology analyzer. Biochemical markers including serum uric acid, urea, creatinine, phosphate, alanine aminotransferase (ALT), and gamma glutamyltransferase (GGT) were measured on a Selectra E auto analyzer. Serum malondialdehyde (MDA) was measured spectrophotometrically and C-reactive protein (CRP) on Immulite-1000. Results revealed that lead-exposed workers had significantly high BLLs, median (range), 29.1 (9.0-61.1) microg/dL compared with controls, 8.3 (1.0-21.7) microg/dL. Oxidative stress (MDA, GGT) and inflammatory markers (high-sensitivity CRP) were significantly increased (P < or = 0.05). Blood pressure was raised, whereas hemoglobin was decreased in exposed group (P < or = 0.002). Serum urea, uric acid, phosphate, and ALT were significantly raised in lead-exposed workers (P < or = 0.001). Serum albumin, total proteins, and glomerular filtration rate (GFR) were decreased. Blood lead showed a significant positive correlation with serum GGT (r = 0.63), MDA (r = 0.71), CRP (r = 0.75), urea (r = 0.34), creatinine (r = 0.51), and uric acid (r = 0.29) (P < or = 0.01). It is concluded that lead exposure increases oxidative stress that correlates with adverse changes in hematological, renal, and hepatic function in the occupational workers. Elevated blood lead has positive correlation with oxidative stress, inflammatory and biochemical markers that might be used to detect impairment in the body function in lead exposed workers.

Therapeutic drug monitoring of amikacin in preterm and term infants

INTRODUCTION

Amikacin is a commonly-prescribed drug used for the empirical treatment of bacterial infections in neonates. A marked change in the pharmacokinetics of amikacin has been reported during neonatal life. Amikacin has a very narrow therapeutic range and can cause very serious side effects such as nephrotoxicity and ototoxicity. The current therapeutic dose of amikacin, i.e. 15 mg/kg of body weight, may increase the risk of toxicity in preterm infants with immature renal functions. We aimed to determine the frequency of amikacin toxicity in preterm as compared to term infants by measuring its serum trough levels following the administration of the current therapeutic dose.

METHODS

A comparative study was conducted at the neonatal intensive care unit of the Military Hospital, Rawalpindi, Pakistan. A total of 104 infants (52 term and 52 preterm) receiving amikacin at a dose of 15 mg/kg of their body weight, once daily for bacterial infection, were included. After clinical evaluation, serum creatinine levels were measured at admission and on the third day. Amikacin trough levels were taken after 72 hours of therapy and measured on the TDx Abbot Drug Analyser.

RESULTS

The gestational age range was 37-40 weeks in term and 29-36 weeks in preterm infants. The term and preterm infants had a median weight of 2.8 kg and 2.1 kg, respectively. The preterm infants had significantly higher median (range) 11.33 (1.50-42.60) ug/ml levels of serum amikacin as compared to 8.5 (2.8-33.0) ug/ml in term infants (p-value is less than 0.01). The preterm infants had a high frequency of toxic 32 (62 percent) and subtherapeutic 12 (23 percent) levels, as compared to 11 (21 percent) and 5 (10 percent) in term infants, respectively. Serum amikacin levels revealed a positive correlation with post-dose serum creatinine (r equals 0.48; p-value is less than 0.05).

CONCLUSION

This study demonstrated that the current practice of amikacin treatment for bacterial infection needs to be adjusted due to unique pharmacokinetic variability in preterm infants. There is a need for regular therapeutic drug monitoring and renal function assessment in all infants receiving amikacin therapy in order to avoid nephrotoxicity.

Anaemia and cancer treatment: a conceptual change

Anaemia is the most common haematological abnormality in cancer patients, and unfortunately, it is often under-recognised and undertreated. The aetiopathology of anaemia in cancer patients is complex and is usually multifactorial. There is enough evidence suggesting that tumour hypoxia in anaemic patients has a negative impact on the treatment outcomes in cancer patients. The use of recombinant human erythropoietin is becoming a new standard of care in cancer patients. Various well-controlled studies have shown that the use of erythropoietin (EPO) increases the haemoglobin level, thereby decreasing the need for frequent transfusions and improving the tumour responses, cancer-free survival and quality-of-life parameters in cancer patients. However, a few recent clinical trials failed to replicate the survival benefit. Hence, a free unrestricted use of EPO is to be avoided. The past belief that anaemia does not matter in cancer patients is now considered invalid and is being seriously challenged. This article aims to present some recent findings on the impact of anaemia on outcomes, with discussion on the possible causes and effects. The benefits of the use of EPO analogues in cancer-related anaemia are also presented.

Vasopressin for the management of catecholamine-resistant anaphylactic shock

Severe anaesthetic anaphylaxis is relatively uncommon. Oxygen, fluids and epinephrine are considered to be the mainstay for treatment of cardiovascular collapse and current guidelines for the management of anaphylaxis list only epinephrine as a vasopressor to use in the event of a cardiovascular collapse. Recently, evidence has emerged in the support of the use of vasopressin in cardiopulmonary resuscitation; it is also recommended for the treatment of ventricular fibrillation, septic shock and post-cardiopulmonary bypass distribution shock. Currently, there is no algorithm or guideline for the management of anaphylaxis that include the use of vasopressin. We report a 24-year-old woman who developed severe anaphylactic shock at induction of anaesthesia while undergoing laparoscopic cholecystectomy. Circulation shock was refractory to epinephrine and high doses of pure alpha-agonist phenylephrine and norepinephrine. Single intravenous dose of two units of vasopressin re-established normal circulation and blood pressure.

Resetting the detection level of cord blood thyroid stimulating hormone (TSH) for the diagnosis of congenital hypothyroidism

An appraisal of a 17-year primary thyroid stimulating hormone (TSH) screening programme for the detection of congenital hypothyroidism was carried out to establish the reference interval of cord blood TSH in unaffected infants; the mean cord blood TSH concentration of affected infants and the incidence of congenital hypothyroidism in the Najran province of Saudi Arabia. Our findings show a reference interval of cord blood TSH of 2.0-16.8 mU/l in unaffected infants; a mean cord blood TSH concentration of 399 mU/l in affected infants; a false positive rate for the diagnosis of at-risk infants of 1.02% and a congenital hypothyroidism incidence rate of 34/100 000 (1 : 2931) live births. These findings suggest that there is a need to reset the cord blood TSH concentration for the detection of at-risk infants. We suggest that the detection level of cord blood TSH for the recognition of at-risk infants can be set at 90 mU/l rather than the recommended level of 30 mU/l. This should reduce the false positive rate for detection of infants at risk of congenital hypothyroidism.

Widow inheritance and HIV/AIDS in rural Uganda

Despite current efforts to combat HIV/AIDS through behavioural change, ingrained socio-cultural practices such as widow inheritance in south-western Uganda has not changed. Low education, unemployment, dowry, widows' socioeconomic demands and the inheritor's greed for the deceased's wealth, influence widow inheritance. Voluntary counselling and testing is needed for the widows and their inheritors; formal dowry should be removed from marriage and widow inheritance stripped of its sexual component.

Role of radiotherapy in early breast cancer: an overview

Radiotherapy has an established role in reducing the local relapses in breast cancer patients. The objective of this review was to investigate whether radiotherapy or its omission after breast surgery has measurable consequences on local tumor recurrence and patient survival. The late excess of cardiac deaths has also been published in various reports but important advances in the delivery of radiotherapy have overcome this problem to the extent that, excess cardiac deaths do not appear to be occurring in more recent trials. In this article some recent data, suggesting that radiotherapy following mastectomy and/or breast conserving surgery has a beneficial effect on survival is reviewed. Omission of radiotherapy is associated with a large increase in risk of ipsilateral breast tumor recurrence and with a small increase in the risk of patient's mortality.

Customer focused incident monitoring in anaesthesia

The database of incident forms relating to anaesthesia services in an institutional risk management programme were reviewed for 2003-2005, the aim being to identify any recurring patterns. Incidents were prospectively categorised as relating to attitude/behaviour, communication breakdown, delay in service, or were related to care, cost, environment, equipment, security, administrative process, quality of service or miscellaneous. The total number of anaesthesia-related incidents reported during the period was 287, which related to 0.44% of the total number of anaesthetics administered during the time period. In all, 170 incidents were reported by the department, 96 by internal customers and 21 by external customers. Only 30% of the complaints came from the operating room. Thirty-four per cent of all incidents related to communication, behaviour and delay in service. A requirement to teach communication skills and stress handling formally in anaesthesia training programmes, and at the time of induction of staff into the department, has been identified.

Factors influencing the choice of anesthesia as a career in a developing country

Career choice in medicine is influenced by several factors. Our aim was to look at reasons for choice of anesthesia as a career in a cohort of doctors applying for the residency training in a university hospital in a developing country. A semi-structured interview form is used in our department and includes a question related to career choice. Each applicant is interviewed by two faculty members independently. All interview forms between 1992 to 2004 were reviewed and the reason for choosing anesthesia was coded in different categories. The sample consisted of 167 applicants and 334 forms. There were 29 females and 138 males. The mean age of the applicants was 28 years. Sixty two percent chose anesthesia because of general interest and nature of the specialty, 24% of these mentioned had no specific reasons, 17% thought the specialty was intellectually challenging, 8% liked the technical aspect, 5% were interested in physiology and pharmacology, 2% liked the operating room environment, and 6% liked the immediate results. The second major group (36%) cited the reason as better economic opportunities. Sixteen percent were influenced by friends or relatives in their choice. Twenty six percent chose anesthesia primarily because of their interest in critical care, pain management or emergency management. Our data indicates that selection of career in anesthesia in our county is strongly related to the nature of specialty and future employment opportunities. A significant number were influenced by family and friends. This pattern is different from that reported from Australia and United States.

Dengue haemorrhagic fever with unusual prolonged thrombocytopaenia

We describe a case of dengue haemorrhagic fever with prolonged thrombocytopaenia. A 22-year-old Malay man with no prior illness presented with a history of fever and generalised macular rash of four days duration. Initial work-up suggested the diagnosis of dengue haemorrhagic fever based on thrombocytopaenia and positive dengue serology. Patient recovered from acute illness by day ten, and was discharged from the hospital with improving platelet count. He was then noted to have declining platelet count on follow-up and required another hospital admission on day 19 of his illness because of declining platelet count. The patient remained hospitalised till day 44 of his illness and managed with repeated platelet transfusion and supportive care till he recovered spontaneously.

Radiation exposure of trainee anaesthetists

This prospective study was conducted to determine the level of radiation exposure of trainee anaesthetists working in urology, orthopaedics and radiology environments. Anaesthetists wore lithium fluoride thermoluminescent dosimeter (TLD) badges over a 6-month period. The position of badges was standardised at the collar site (TLD1) and at waist level (TLD2). Area specific dosimeters were used and exchanged between anaesthetists. Of a total of 723 procedures, anaesthetists were exposed to radiation in 33% of procedures in orthopaedics, 30% in urology and 39% in radiology. The mean (SD) exposure time to radiation per case was significantly greater in orthopaedics than in urology (9.2 (4) min vs. 4.2 (2) min). The radiation exposure per case was highest in radiology (19.2 (22) min). The net combined exposure over a 6-month period was 0.2177 mSv in urology, 0.4265 mSv in orthopaedics and 3.8457 mSv in radiology. The combined exposure was less than the 20 mSv recommended as the maximum exposure per year. Our data does not support the need for routine dosimetric monitoring of anaesthetists working in the above settings.

An audit of postoperative minor complications of anesthesia

OBJECTIVE

To look at minor complications attributable to anesthesia in adult surgical patients at our Institution and to identify various contributing factors.

DESIGN

Descriptive cross sectional audit.

SETTING

Aga Khan University Hospital, Karachi, Pakistan.

STUDY PARTICIPANTS

Seven hundred and thirty surgical patients undergoing elective surgery were recruited.

INTERVENTIONS

This was a non-interventional study and data was collected prospectively based on predefined criteria.

MAIN OUTCOME MEASURES

The incidence of nausea, vomiting, sore throat, headache, drowsiness, phlebitis, dizziness, myalgia, transient nerve palsy, conjunctivitis, ringing of ears, low backache, lip injury, dental injury or any other minor complications were looked at.

RESULTS

Nausea, sore throat and vomiting were the highest reported complications. The incidence of nausea, drowsiness and dizziness was less in patients more than sixty years of age. Incidence of nausea and vomiting was higher in ASA 1 patients and in surgery lasting less than ninety minutes. Headache and dizziness were reported high in certain surgical specialties.

CONCLUSION

The overall rate of minor complications following anesthesia was 12.6%. No complications were reported by 30% of the study population. The data has given us a benchmark for patient information and will be used for risk reduction in our Department of Anaesthesiology.

PSA recurrence following radical prostatectomy is comparable for all age groups in the UK

Increasing numbers of men are being diagnosed with prostate cancer and undergo operative curative treatment. It has been suggested that outcome after radical prostatectomy (RP) may vary for different age groups.

OBJECTIVE

To investigate whether PSA recurrence-free survival after RP is related to age at operation for a cohort of English men.

METHODS

A total of 854 patients notes from four Urology units were audited for preoperative staging parameters and follow-up data obtained. The relationship of PSA, age, biopsy Gleason grade, clinical stage, era and institution on PSA recurrence-free survival was competitively assessed with a multivariate model.

RESULTS

Only preoperative PSA (P<0.0001) and biopsy Gleason grade (P < 0.0001) were found to be strongly associated with PSA recurrence-free survival on multivariate analysis. PSA recurrence-free survival probabilities at 5 y for patients aged 45-55 y, 55.1-60 y, 60.1-65 y, 65.1-70 y and 70.1-75 y were 0.59 (CI 0.47-0.71), 0.74 (CI 0.64-0.784), 0.56 (CI 0.44-0.68), 0.61 (CI 0.53-0.69) and 0.60 (CI 0.46-0.74), respectively. No significant difference of PSA recurrence-free survival between any of the age groups was found (Log-rank, P = 0.8567).

CONCLUSION

No significant difference of pathological variables or biochemical recurrence across the age groups was found. The widely held belief of poorer outcome in younger men selected for RP does not seem to be borne out by this study.

Contemporary update of cancer control after radical prostatectomy in the UK

Despite a significant increase of the number of radical prostatectomies (RPs) to treat organ-confined prostate cancer, there is very limited documentation of its oncological outcome in the UK. Pathological stage distribution and changes of outcome have not been audited on a consistent basis. We present the results of a multicentre review of postoperative predictive variables and prostatic-specific antigen (PSA) recurrence after RP for clinically organ-confined disease. In all, 854 patient's notes were audited for staging parameters and follow-up data obtained. Patients with neoadjuvant and adjuvant treatment as well as patients with incomplete data and follow-up were excluded. Median follow-up was 52 months for the remaining 705 patients. The median PSA was 10 ng ml⁻¹. A large migration towards lower PSA and stage was seen. This translated into improved PSA survival rates. Overall Kaplan–Meier PSA recurrence-free survival probability at 1, 3, 5 and 8 years was 0.83, 0.69, 0.60 and 0.48, respectively. The 5-year PSA recurrence-free survival probability for PSA ranges <4, 4.1–10, 10.1–20 and >20 ng ml⁻¹ was 0.82, 0.73, 0.59 and 0.20, respectively (log rank, P<0.0001). PSA recurrence-free survival probabilities for pathological Gleason grade 2–4, 5 and 6, 7 and 8–10 at 5 years were 0.84, 0.66, 0.55 and 0.21, respectively (log rank, P<0.0001). Similarly, 5-year PSA recurrence-free survival probabilities for pathological stages T2a, T2b, T3a, T3b and T4 were 0.82, 0.78, 0.48, 0.23 and 0.12, respectively (log rank, P=0.0012). Oncological outcome after RP has improved over time in the UK. PSA recurrence-free survival estimates are less optimistic compared to quoted survival figures in the literature. Survival figures based on pathological stage and Gleason grade may serve to counsel patients postoperatively and to stratify patients better for adjuvant treatment.

Drug related critical incidents

Drug related incidents are a common form of reported medical errors. This paper reviews the critical incidents related to drug errors reported from the main operating theatre suite in a teaching hospital in a developing country from January 1997 to December 2002. Each report was evaluated individually by two reviewers using a structured process. During this period, 44 874 anaesthetics were administered; 768 critical incidents were reported, 165 (21%) of which were related to drug errors. Underdosage, side-effect/drug reaction and syringe swap were the most common. A total of 76% were classified as preventable; 56% due to human error and 19% due to system error. High risk incidents accounted for 10% of all drug errors and most of these were related to the use of neuromuscular blocking drugs. This analysis has been found useful in addressing some issues about priorities.

Case Selection for Radical Prostatectomy in the UK

INTRODUCTION

Radical prostatectomy is an increasingly popular treatment option for clinically localised prostate cancer, yet PSA outcome figures are rare in the UK. This makes it difficult to establish appropriate criteria for case selection. We conducted an audit of PSA recurrence of 5 large centres in the south of England and investigated the use of pre-operative PSA to improve case selection and outcome.

METHOD

854 patients notes were audited for pre-operative staging parameters and follow-up data obtained. Patients with neoadjuvant and adjuvant treatment as well as patients with incomplete data and follow-up were excluded.

RESULT

Median follow-up was 52 months for the remaining 663 patients. Median PSA was 10 ng/ml. A large improvement of PSA recurrence free survival rates was observed from 1988 to 1998 as a result of change in case selection and stage migration. Overall Kaplan-Meier PSA recurrence free survival probability at 1, 3, 5 and 8 years was 0.83, 0.69, 0.60 and 0.48, respectively. Five-year PSA recurrence free survival probability for PSA ranges <4 ng/ml, 4.1-10 ng/ml, 10.1-20 ng/ml and >20 ng/ml was 0.82, 0.73, 0.59 and 0.20, respectively (Wilcoxon, p < 0.0001). A simulation of biochemical recurrence free survival for patient cohorts with stepwise reduced inclusion PSAs suggests an improved outcome for patients with a pre-operative inclusion PSA of <12 ng/ml. Further reduction of the inclusion PSA does not improve outcome.

CONCLUSION

Intermediate PSA recurrence free survival has improved over time in England. PSA recurrence free survival estimates are less optimistic compared to frequently quoted American figures. A reduced pre-operative PSA cut-off for case selection may be used to improve outcome.

Low cost quality control human serum: method of preparation, validation of values and its comparison with the commercial control serum

OBJECTIVE

To prepare low-cost quality controls (QC) human serum and scientifically evaluate its advantages/disadvantages when compared with commercially available sera.

METHODS

The home made QC serum was prepared as per WHO recommended protocol from four healthy volunteers. It was screened for HIV, HCV and HBV, pooled together and stabilized with ethylene glycol. The initial 40 values were used for calculation of means, SDs and CVs for seventeen routinely measured analytes and results were compared with those of commercially available lyophilized human sera.

RESULTS

The average concentrations of seventeen commonly analyzed constituents were found to be near the middle of the physiological range of healthy subjects and the home made serum could be a good substitute for the commercial serum of normal range. The narrower CVs of the analytes imply a lesser vial to vial variation in the home made sera. Additional advantages include easy preparation, no need for reconstitution and lower cost.

CONCLUSION

Home made serum is a good substitute for the commercial serum of the normal range especially in developing countries like Pakistan.

Time trends in case selection, stage and prostate-specific antigen recurrence after radical prostatectomy: a multicentre audit

OBJECTIVES

To report an audit of preoperative staging variables, case selection, stage migration and prostate-specific antigen (PSA) recurrence at five large centres in the south of England. To establish PSA outcome values after radical prostatectomy for clinically localized prostate cancer in the UK, and enable appropriate patient counselling.

PATIENTS AND METHODS

The notes of 854 patients were audited for preoperative staging variables and follow-up data obtained. Patients with neoadjuvant and adjuvant treatment, and with incomplete data and follow-up, were excluded.

RESULTS

The median follow-up was 52 months for the remaining 663 patients; the median PSA level was 10 ng/mL. There was a large migration towards lower PSA and stage; this translated into improved PSA survival rates. The overall Kaplan-Meier PSA recurrence-free survival probability at 1, 3, 5 and 8 years was 0.83, 0.69, 0.60 and 0.48, respectively. The 5-year PSA recurrence-free survival probabilities for PSA levels of < 4, 4.1-10, 10.1-20 and > 20 ng/mL were 0.82, 0.73, 0.59 and 0.20, respectively (Wilcoxon, P < 0.001). The PSA recurrence-free survival probabilities for biopsy Gleason grade 2-4, 5 and 6, 7 and 8-10 at 5 years were 0.70, 0.61, 0.55 and 0.21, respectively (Wilcoxon, P < 0.001). Similarly, the 5-year PSA recurrence-free survival probabilities for clinical stages T1a and 1b, T1c, T2a and T2b were 0.79, 0.62, 0.57 and 0.44, respectively (Wilcoxon, P = 0.0012).

CONCLUSION

With better case selection the intermediate oncological outcome has improved over time in the UK. PSA recurrence-free survival estimates are less optimistic than the frequently quoted American values. The present values may be used to help in counselling British patients before radical prostatectomy.

Midazolam and thiopentone co-induction: looking for improvement in quality of anaesthesia

OBJECTIVE

To evaluate improvement in quality of anaesthesia induction using thiopentone and midazolam for co-induction of anaesthesia. An additional end point was taken as loss of response to a tetanic stimulation (50 Hz) delivered for 5 seconds after the loss of verbal contact and eyelash reflex.

METHODS

Ninety ASA I and II patients, within the age range of 20-60 years were studied. Patients were randomly divided into three equal groups; A, B and group C.

RESULTS

Onset of induction and loss of response to a tetanic stimulation was achieved earlier in group B as compared to the other study groups (p<0.05).

CONCLUSION

Co-induction with midazolam 0.02 mg x kg(-1) followed by thiopentone 3 mg x kg(-1) was superior to other two groups. Induction of anaesthesia in this group was found to be smoother and faster, provided better hemodynamic stability, better airway maintenance and with lesser incidence of untoward effects.

A comparison of morphine and nalbuphine for intraoperative and postoperative analgesia

INTRODUCTION

Short acting narcotics are not available in Pakistan and the supply of drugs like morphine and pethidine is short and erratic; therefore there is a need for investigating acceptable alternatives for analgesia, to be used for balanced anaesthesia.

OBJECTIVE

We studied the agonist-antagonist narcotic nalbuphine compared to morphine, for intra and postoperative pain relief in total abdominal hysterectomies.

METHODS

In a randomised double blind trial, fifty ASA I and II patients in two groups of twenty five each were given equianalgesic doses of morphine and nalbuphine. Hemodynamic stability, intraoperative analgesia, recovery profiles, incidence of side effects and need for postoperative supplements were compared using standard anaesthesia technique for induction, maintenance and reversal. Postoperative analgesia profile was studied by the need for supplements in twenty four hours using the unidimensional verbal category scale.

RESULTS

We found that patients in the morphine group showed a rise of mean blood pressure and heart rate to 20% above the baseline in response to intubation whereas in the nalbuphine group it remained within 20% of baseline. Twelve out of twenty five patients in the morphine group and four out of twenty five patients in the nalbuphine group needed intraoperative supplements. Recovery profiles were similar in the two groups; postoperative nausea and vomiting and need for postoperative supplements was significantly less in the nalbuphine group.

CONCLUSION

We conclude that nalbuphine provides better haemodynamic stability and better analgesia, recovery profile and postoperative pain relief compared to morphine in patients undergoing total abdominal hysterectomy.
