Abstract
OBJECTIVES Keep Well, an anticipatory care programme which commenced in Scotland in 2006, aims to reduce health inequalities through holistic health checks in primary care in deprived communities. A new, non-clinical outreach worker role was created to provide support and signposting to Keep Well patients following their health check. There is currently little evidence regarding how the role is perceived. The aim of this study was to understand how staff and patients view the Keep Well outreach worker role. STUDY DESIGN A qualitative interview-based study was carried out between July and October 2010. METHODS One-to-one interviews were conducted with 12 Keep Well staff and four patients. Interviews were transcribed, coded and analysed using a thematic analysis approach. RESULTS The outreach worker role was viewed positively, particularly in terms of partnership working with practices and local services, and the benefits of support to patients. Referring patients to outreach workers reduced pressure on staff, who were able to spend more time on patients' physical health rather than mental health or lifestyle support. Support from an outreach worker enabled patients to make changes to their life and their health. Concerns were about staff turnover, poor referral rates, set-up of the project and misinterpretation of the role. CONCLUSION Patients and staff perceive benefits from the outreach worker role in providing motivational support to patients from deprived areas.

Abstract
Many aspects of hypertension care outside pregnancy may be applied in pregnancy, but little information is available on which to base decision-making. It would seem reasonable to continue previous dietary salt restriction and physical activity in women with pre-existing (and controlled) hypertension, encourage a heart-healthy diet in all women with a hypertension disorder of pregnancy, and take patient preference into account when deciding on place of care. Although bed rest has become a key part of obstetric practice and for care of women with a hypertension disorder of pregnancy, in particular, the evidence is lacking to support this practice. This may also increase thromboembolic risk. Antihypertensive treatment is strongly advised for women with severe hypertension. The most common agents are parenteral labetalol, hydralazine, or oral nifedipine capsules. Clinicians should familiarise themselves with multiple agents. Until the role of antihypertensive treatment for non-severe hypertension in pregnancy is clarified by ongoing research, clinicians should explicitly state an individual patient's blood pressure goal, which could reasonably be anywhere between 130/80 and 155/105 mmHg. Labetalol and methyldopa are used most commonly. Breastfeeding should be encouraged. Many risk factors for hypertension (e.g. obesity), as well as hospitalisation and pre-eclampsia, all increase the thromboembolic risk for pregnant women, and care providers should consider thromboprophylaxis in the appropriate setting. Finally, anaesthetists play a critical role in the management of women with a hypertension disorder of pregnancy, and should be involved earlier rather than later in the course of their care.

Abstract
Parturients have the greatest risk of postdural puncture headache. use of a pencil-point needle, such as the 25 gauge Whitacre, has been associated with a lower incidence of PDPH. This observational study of 1009 obstetrical patients assessed possible factors related to the incidence of PDPH and other complications associated with spinal anesthesia using the 25 gauge Whitacre needle. The independent variables included procedure, maternal position at insertion, ease of insertion, intraoperative i.v. analgesia supplementation, use of intrathecal narcotics, parity and type of local anesthetic. Patients were followed daily during their hospitalization and questioned specifically about the presence of headache, its nature, onset and treatment. Two hundred and twenty-nine patients developed a headache postperatively but only 25 had postdural puncture headaches (overall incidence 2.5%). The PDPH typically presented on day 2 (median), range 1-4). Six patients (0.59%) required epidural blood patch. There were eight (0.8%) failed finals which were converted to general anesthesia. None of the factors evaluated were significant in predicting the occurrence of PDPH.

Abstract
In this randomized double-blind trial we investigated the effect of acupressure on the incidence of nausea and vomiting after caesarean section under spinal anaesthesia with added intrathecal morphine. Parturients wore either acupressure or placebo wristbands during surgery and postoperatively for at least 10 h. There was no significant difference overall between the two groups in the incidence of intra- or postoperative nausea or vomiting/retching. Demand for antiemetic medication was also similar in the two groups. However, in the sub-group of parturients who gave a previous history of postoperative nausea or vomiting, there was a statistically significant reduction in both postoperative nausea and vomiting/retching in the acupressure group. Further investigations are needed to see whether acupressure may be an effective non-pharmacological, non-invasive treatment for a common problem in this sub-group of patients.

Abstract
The Consolidated Standards for Reporting of Trials (CONSORT) checklist is an evidence-based approach to help improve the quality of reporting randomised controlled trials. The purpose of this study was to determine how closely randomised controlled trials in obstetric anaesthesia adhere to the CONSORT checklist. We retrieved all randomised controlled trials pertaining to the practice of obstetric anaesthesia and summarised in Obstetric Anesthesia Digest between March 2001 and December 2002 and compared the quality of reporting to the CONSORT checklist. The median number of correctly described CONSORT items was 65% (range 36% to 100%). Information pertaining to randomisation, blinding of the assessors, sample size calculation, reliability of measurements and reporting of the analysis were often omitted. It is difficult to determine the value and quality of many obstetric anaesthesia clinical trials because journal editors do not insist that this important information is made available to readers. Both clinicians and clinical researchers would benefit from uniform reporting of randomised trials in a manner that allows rapid data retrieval and easy assessment for relevance and quality.

Abstract
BACKGROUND Dextromethorphan is an N-methyl-D-aspartic acid antagonist which can attenuate acute pain with few side-effects. In this prospective, randomized, double-blind study of dextromethorphan and intrathecal morphine, we investigated postoperative pain, pruritus, nausea and vomiting in women undergoing Caesarean section under spinal anaesthesia. METHODS Women were allocated randomly to one of six groups, to receive intrathecal morphine 0.05, 0.1 or 0.2 mg plus oral dextromethorphan 60 mg or placebo. RESULTS The addition of dextromethorphan did not reduce postoperative pain scores (P=0.83). Compared with women receiving intrathecal morphine 0.05 mg, women receiving higher doses had a significantly higher incidence of nausea and vomiting [odds ratio for intrathecal morphine 0.1 mg, 4.0 (95% confidence interval 1.2-14.1); for intrathecal morphine 0.2 mg, 7.9 (2.3-27.1)]. Compared with women receiving intrathecal morphine 0.05 mg, women receiving higher doses also had a significantly higher incidence of pruritus [odds ratio for intrathecal morphine 0.1 mg, 3.2 (95% confidence interval 1.3-8.2); for intrathecal morphine 0.2 mg, 3.7 (1.4-9.5)]. Women receiving dextromethorphan had a lower incidence of nausea and vomiting [odds ratio 2.6 (1.1-6.3)]. CONCLUSIONS Postoperative pain after Caesarean section under spinal anaesthesia was not reduced by the addition of oral dextromethorphan to a multimodal approach including intrathecal morphine.

Abstract
Health impact assessment (HIA) can be used to examine the relationships between inequalities and health. This HIA of Edinburgh's transport policy demonstrates how HIA can examine how different transport policies can affect different population groupings to varying degrees. In this case, Edinburgh's economy is based on tourism, financial services and Government bodies. These need a good transport infrastructure, which maintains a vibrant city centre. A transport policy that promotes walking, cycling and public transport supports this and is also good for health. The HIA suggested that greater spend on public transport and supporting sustainable modes of transport was beneficial to health, and offered scope to reduce inequalities. This message was understood by the City Council and influenced the development of the city's transport and land-use strategies. The paper discusses how HIA can influence public policy.

Abstract
We present our experience in the anesthetic management of two parturients with pseudoxanthoma elasticum. The first had an epidural catheter inserted for labor analgesia and ultimately had a forceps delivery. The second had a cesarean section under epidural anesthesia and had a complicated postoperative course. There were no untoward effects of regional anesthesia in either of these two women. The anesthetic implications for parturients with pseudoxanthoma elasticum are discussed.

Abstract
BACKGROUND Pain from episiotomy or tearing of perineal tissues during childbirth is often poorly treated and may be severe. This randomized double-blind controlled trial was performed to compare the effectiveness, side effects and cost of, and patient preference for, 2 analgesics for the management of postpartum perineal pain. METHODS A total of 237 women who gave birth vaginally with episiotomy or a third- or fourth-degree tear between August 1995 and November 1996 at a tertiary-level teaching and referral centre for obstetric care in Vancouver were randomly assigned to receive either ibuprofen (400 mg) (n = 127) or acetaminophen (600 mg) with codeine (60 mg) and caffeine (15 mg) (Tylenol No. 3) (n = 110), both given orally every 4 hours as necessary. Pain ratings were recorded before the first dose and at 1, 2, 3, 4, 12 and 24 hours after the first dose on a 10-cm visual analogue scale. Side effects and overall opinion were assessed at 24 hours. RESULTS Ibuprofen and acetaminophen with codeine had similar analgesic properties in the first 24 hours post partum (mean pain rating 3.4 and 3.3, mean number of doses in 24 hours 3.4 and 3.3, and proportion of treatment failures 13.8% [16/116] and 16.0% [16/100] respectively). Significantly fewer subjects in the ibuprofen group than in the acetaminophen with codeine group experienced side effects (52.4% v. 71.7%) (p = 0.006). There were no significant differences in overall patient satisfaction between the 2 groups. The major determinant of pain intensity was forceps-assisted delivery. Overall, 78% of the treatment failures were in women with forceps-assisted deliveries. INTERPRETATION Since the 2 analgesics were rated similarly, ibuprofen may be the preferred choice because it is less expensive and requires less nursing time to dispense. Further studies need to address improved analgesia for women with forceps-assisted deliveries.

Abstract
OBJECTIVE Health Impact Assessment (HIA) provides a method of predicting the health impacts of policies and activities, in order to recommend changes that would improve health. We piloted approaches to health impact assessment and made recommendations for its use as part of the planning and policy making processes in Scotland. DESIGN Two Health Impact Assessments were done as case studies. One assessed the City of Edinburgh Council's Local Transport Strategy. The other assessed North Edinburgh Area Renewal Housing Strategy. Both were done in partnership with the professionals responsible for developing the strategies. RESULTS The main health impacts of transport strategy were in the areas of: accidents, pollution, access to amenities, jobs and social contacts, opportunities for physical activity in walking and cycling and impacts on community networks. Overall, housing strategy impacted most on mental health, especially stress and depression. The recommendations of both HIAs are being used in developing the strategies further. CONCLUSIONS Health impact assessment can make explicit the health consequences of decisions in different sectors, including impacts on health inequalities. Health Impact Assessment should be done as part of community planning and other partnership activities. Consideration of health impacts should become part of routine decision making.

Abstract
BACKGROUND Policies and practice in many sectors affect health. Health impact assessment (HIA) is a way to predict these health impacts, in order to recommend improvements in policies to improve health. There has been debate about appropriate methods for this work. The Scottish Executive funded the Scottish Needs Assessment Programme to conduct two pilot HIAs and from these to develop guidance on HIA. METHODS Case study 1 compared three possible future scenarios for developing transport in Edinburgh, based on funding levels. It used a literature review, analysis of local data and the knowledge and opinions of key informants. Impacts borne by different population groups.were compared using grids. Case study 2 assessed the health impacts of housing investment in a disadvantaged part of Edinburgh, using published literature, focus groups with community groups and interviews with professionals. RESULTS Disadvantaged communities bore more detrimental effects from the low transport investment scenario, in the areas of: accidents; pollution; access to amenities, jobs and social contacts; physical activity; and impacts on community networks. The housing investment had greatest impact on residents' mental health, by reducing overcrowding, noise pollution, stigma and fear of crime. CONCLUSION Although there is no single 'blueprint' for HIA that will be appropriate for all circumstances, key principles to inform future HIA were defined. HIA should be systematic; involve decision-makers and affected communities; take into account local factors; use evidence and methods appropriate to the impacts identified and the importance and scope of the policy; and make practical recommendations.

Abstract
PURPOSE To describe the anesthetic and obstetrical management of a pregnant patient with co-existing Familial Hypokalemic Periodic Paralysis (FHPP) and Wolff-Parkinson-White syndrome (WPW). CLINICAL FEATURES A 29 yr-old primigravida with FHPP and WPW presented to the antenatal clinic at 18 wk gestation, for consideration of her anesthetic and obstetrical management during labour and delivery. A plan was constructed to avoid the known precipitating factors of FHPP including carbohydrate loading, cold, mental stress and exercise, which could lead to acute attacks of weakness. She presented for induction of labour at 41 wk and three days. An epidural catheter was sited early in labour. The second stage was limited to less than one hour. She had a rotational forceps delivery for which the epidural was extended to provide anesthesia. A healthy male baby was delivered. The patient made an uncomplicated recovery and was discharged home on the second postnatal day. The peripartum potassium was kept within the normal range with intravenous as well as oral potassium supplementation. No arrhythmias were reported. CONCLUSION Assessment of the patient at an early stage in her pregnancy allowed for a multidisciplinary approach to this patient and her medical problems. A plan was made to avoid known precipitating factors during labour, delivery and the postnatal period well in advance of her date of confinement, leading to a successful outcome for mother and child.

Abstract
Neuraxial opioids were first used for labour analgesia in 1980 following the description of spinal cord opioid receptors in 1979. Via these receptors in the dorsal horn, opioids modulate both the visceral and the somatic pain of labour. The onset and duration of action of the individual opioid are determined primarily by its relative lipid solubility. Neuraxial opioids have a local anaesthetic sparing effect, allowing the use of lower concentrations of both agents while maintaining analgesia. As a sole agent, intrathecal opioids can be used to provide analgesia during the first stage of labour, especially in the high-risk parturient. They also have a role in the management of perineal pain and the provision of rapid-onset analgesia. Unfortunately maternal and neonatal side-effects can occur, the most important being respiratory depression.

Abstract
PURPOSE To review the current literature and generate recommendations on the role of newer technology in the management of the unanticipated difficult airway. METHODS A literature search using key words and filters of English language and English abstracted publications from 1990-96 contained in the Medline, Current Contents and Biological Abstracts databases was carried out. The literature was reviewed and condensed and a series of evidence-based recommendations were evolved. CONCLUSIONS The unanticipated difficult airway occurs with a low but consistent incidence in anaesthesia practice. Difficult direct laryngoscopy occurs in 1.5-8.5% of general anaesthetics and difficult intubation occurs with a similar incidence. Failed intubation occurs in 0.13-0.3% general anaesthetics. Current techniques for predicting difficulty with laryngoscopy and intubation are sensitive, non-specific and have a low positive predictive value. Assessment techniques which utilize multiple characteristics to derive a risk factor tend to be more accurate predictors. Devices such as the laryngeal mask, lighted stylet and rigid fibreoptic laryngoscopes, in the setting of unanticipated difficult airway, are effective in establishing a patient airway, may reduce morbidity and are occasionally lifesaving. Evidence supports their use in this setting as either alternatives to facemask and bag ventilation, when it is inadequate to support oxygenation, or to the direct laryngoscope, when tracheal intubation has failed. Specifically, the laryngeal mask and Combitube have proved to be effective in establishing and maintaining a patent airway in "cannot ventilate" situations. The lighted stylet and Bullard (rigid) fibreoptic scope are effective in many instances where the direct laryngoscope has failed to facilitate tracheal intubation. The data also support integration of these devices into strategies to manage difficult airway as the new standard of care. Training programmes should ensure graduate physicians are trained in the use of these alternatives. Continuing medical education courses should allow physicians in practice the opportunity to train with these alternative devices.

Abstract
PURPOSE To report the management of labour analgesia and subsequent anaesthesia for postpartum bleeding in a 19-yr-old parturient with Noonan's syndrome. CLINICAL FEATURES The patient presented in active labour at 36-wk gestation. She was known to have Noonan's syndrome and had been assessed regularly throughout pregnancy. Features of the syndrome exhibited by the patient included typical facies, chest skeletal abnormalities, pulmonary valve dysplasia, mental retardation and lymphoedema. In addition, she had Factor XI deficiency (0.46 mg.L-1) and thrombocytopenia (92 x 10(9).L-1), previously unreported in a parturient with this syndrome. Although epidural analgesia may have been considered the labour analgesic technique of choice, the risk of epidural haematoma caused by her bleeding diathesis made this unacceptable. This risk was balanced against the possibility of a potentially difficult intubation due to facial abnormalities, should emergency operative delivery become necessary. Labour analgesia was provided with intravenous patient controlled opioid analgesia (fentanyl 25 micrograms bolus, five minute lockout) despite her mental retardation. Dilatation and curettage required general anaesthesia after intubation with awake direct laryngoscopy using cautious sedation. CONCLUSION Noonan's syndrome is characterised by multi-system involvement, requiring thorough preoperative assessment of cardiovascular, skeletal, haematological and central nervous systems. Clotting and platelet defects considerably restrict the possible analgesic and anaesthetic options for labouring patients with this syndrome.

Abstract
OBJECTIVE Concern over transmissible disease has increased interest in methods of minimizing homologous blood transfusion during elective surgery. One method is acute hemodilution, a technique previously unreported in parturients. This study was designed to determine its feasibility and safety in women at risk of hemorrhage during cesarean section. STUDY DESIGN This technique was performed on 38 parturients. Collected blood was retransfused at the end of surgery or earlier, if required. Hemoglobin was measured before hemodilution, after hemodilution, before transfusion, after transfusion, and 24 hours postoperatively. Neonatal assessment included umbilical blood gases and Apgar scores. RESULTS All patients were hemodynamically stable and no fetal heart rate abnormalities were observed during the procedure. One patient received homologous blood and 14 received previously donated autologous blood. Umbilical blood gases were normal and 5-minute Apgar scores were > or = 7. CONCLUSION This study suggests that acute hemodilution is well tolerated in parturients undergoing cesarean section. This may limit exposure to homologous blood transfusion.

Incidence of tissue coring with the 25-gauge Quincke and Whitacre spinal needles. REGIONAL ANESTHESIA 1996; 21:582-5. [PMID: 8956397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 02/03/2023]
Abstract
BACKGROUND AND OBJECTIVES Tissue cores, implanted into the subarachnoid space during subarachnoid injections, can develop into intraspinal lumbar epidermoid tumors. The availability of smaller needles has made spinal anesthesia more popular. Therefore, this prospective, randomized, blinded study was undertaken to determine whether tissue coring occurs with two of the currently used 25-gauge spinal needles. METHODS Fifteen 25-gauge Quincke and seventeen 25-gauge Whitacre spinal needles, in which cerebrospinal fluid (CSF) was not identified and the local anesthetic solution not injected, were obtained from adult male patients undergoing spinal anesthesia. The needles were then evaluated by a pathologist following randomization with similar sterile, unused spinal needles. Twenty additional needles, ten of each type, in which CSF was identified and through which local anesthetic was injected, were also randomized with similar sterile, unused spinal needles and examined. RESULTS Tissue cores were identified in 12 of the 15 Quincke and 7 of the 17 Whitacre spinal needles in which CSF was not identified (P < .05). Of the 20 needles in which CSF was identified and local anesthetic injected, no tissue cores were identified in the 10 Whitacre needles and only one small tissue core was identified in the 10 Quincke needles. All the tissue cores were identified as fat tissue. CONCLUSIONS The 25-gauge Quincke and 25-gauge Whitacre spinal needles currently used in anesthesia can produce tissue coring.

Abstract
This double-blind, randomized study was designed to evaluate the use of indomethacin (Indocid, MSD) following caesarean delivery performed under spinal anaesthesia. Thirty ASA I-II women presenting for elective caesarean were recruited. Spinal anaesthesia was performed in a standard manner using hyperbaric bupivacaine, fentanyl and morphine. At the completion of surgery, subjects were administered two rectal suppositories, followed by 12-hourly suppositories for six doses (three days). The study group received 100 mg indomethacin suppositories and controls were given placebo (Anusol). Data collected included Visual Analog Scale (VAS) pain scores at rest and with movement, VAS scores for nausea and itch, and analgesic use. Demographic data were similar in the two groups. Median time to first analgesia (TTFA) was nine hours in the control group v. 39.5 hours in the indomethacin group (P < 0.003). Additional analgesic requests throughout the postoperative period were less in women who received indomethacin: 4 v 11 (P < 0.001). Women who received indomethacin had significantly less pain on the first postoperative day, especially on movement: mean VAS 1.4 v 5.1 (P < 0.00001). There were no reported adverse neonatal or maternal effects from the use of indomethacin. Rectal indomethacin use following caesarean delivery leads to significantly improved pain relief compared with placebo. The combination of spinal morphine and rectal indomethacin leads to high-quality postoperative analgesia.

Abstract
A case is presented of a woman who, for six years, had been treated for depression with 45 mg daily of the monoamine oxidase inhibitor (MAOI), phenelzine, and who continued taking the drug throughout her pregnancy and labour. Well-documented and potentially fatal interactions between MAOIs and opioids, notably meperidine, meant that her labour analgesia needed careful planning. Opioid- and epinephrine-free epidural bupivacaine analgesia was instituted early with small increments of bupivacaine 0.25% to produce a T10 block, after which an infusion of 8 ml.hr-1 bupivacaine 0.125% was used to maintain analgesia. After 14 hr labour, the epidural was extended uneventfully to allow Caesarean section to be performed for failure to progress. Pressor agents were avoided as indirect-acting drugs can produce severe hypertension. The child appeared normal and the mother had an uncomplicated postoperative course. Epidural analgesia contributed to the safe conduct of labour and Caesarean delivery.

Abstract
A case is presented of a patient who developed fever, leukocytosis, severe back pain, local overlying spinal tenderness, and left leg weakness on the fifth day postpartum. The patient had epidural anaesthesia for ten hours duration, before and during a forceps delivery. Computerized axial tomography (CT) and magnetic resonance imaging (MRI) of the pelvis and lumbar spine revealed swelling of the left iliacus and piriformis muscles, but no epidural abscess. A diagnosis of isolated piriformis pyomyositis with secondary sciatic nerve irritation was made, and the patient was treated with intravenous antibiotics, non-steroidal anti-inflammatory agents, and morphine analgesia. She made a full, uneventful recovery within 50 days, and was discharged requiring no medications.

Abstract
This prospective, randomised, double-blind study compared PCA fentanyl with PCA morphine for post-Caesarean section analgesia. Following a standardised general anaesthetic, 37 women were allocated to receive either fentanyl (n = 18) or morphine (n = 19). The PCA was commenced after the women had been made comfortable in the postanaesthetic recovery room with the appropriate opioid solution (mean dose required = fentanyl 375 micrograms or morphine 16 mg). Initial PCA settings were bolus 1 ml (fentanyl 25 micrograms or morphine 1 mg), lockout time ten minutes, and no background infusion. Both analgesic solutions provided effective analgesia for a mean of 37 hr with high levels of patient satisfaction, and there were no differences in VAS scores for pain and patient satisfaction, or for side effects (nausea, itch, and sleepiness) between fentanyl or morphine. However, more patients in the fentanyl group required supplementary boluses or alterations to the PCA settings (13/18 vs 4/19: P = 0.005), and one patient was removed from the study due to inadequate analgesia. We conclude that fentanyl is not recommended for routine PCA use following Caesarean section.

Abstract
Spinal anaesthesia provides rapid, safe anaesthesia for Caesarean section. The pencil-point spinal needles (Sprotte and Whitacre) are reported to have a low incidence of post-dural puncture headache (PDPH). As the 25G Whitacre is less expensive than the 24G Sprotte needle, this prospective, randomized, double-blind study was designed to compare the incidence of PDPH and ease of insertion of these needles in 304 ASA 1 and 2 women having elective Caesarean section under spinal anaesthesia. Each patient was assessed daily for five consecutive days following Caesarean section by an investigator blinded to the needle used. The results indicate that the two needles have a similar ease of insertion, number of failed insertions, and failed subarachnoid blockade. An inability to insert the spinal needles occurred in two patients in each group. Therefore, 150 patients in each group completed the study. The incidence of PDPH with the 24G Sprotte needle was 4.0% (6/150) compared with 0.66% (1/150) with the 25G Whitacre (NS). There was no correlation between the occurrence of PDPH and the difficulty of needle insertion, presence of transient hypotension or the effectiveness of anaesthesia delivered. This study indicates that both needles are comparable with respect to ease of insertion and incidence of PDPH. As the Whitacre needle is less expensive it is a reasonable alternative to the more expensive Sprotte needle.

Abstract
Cystic fibrosis is an inherited disorder that primarily affects the exocrine glands of the gastrointestinal and respiratory systems. It is commonly diagnosed at birth or shortly thereafter, and until recently few of these patients lived to reproductive age. However, as a result of improved medical care, there are now an increasing number of pregnancies in women with cystic fibrosis. We present the histories of two parturients with cystic fibrosis and discuss the anaesthetic and perinatal implications of this complex disease to their management.
