CORPUS CAVERNOSUM AS AN ALTERNATIVE MEANS OF INTRAVENOUS ACCESS IN THE EMERGENCY SETTING

ANZ JOURNAL OF SURGERY, Issue 7 2000
D. Nicol
Background: The present study was designed to investigate the feasibility of using the corpus cavernosum as an alternative means of intravenous access in the emergency setting. Methods: The feasibility of achieving the infusion flow rates was first ascertained using direct intracavernous infusion of normal saline. The effect of atropine and adrenaline when given via this route was then studied. Hypovolaemic shock was then induced in dogs who were then actively resuscitated via this route using normal saline, Haemaccel and whole blood. Results: Infusion flow rates were achieved for normal saline of 32.3, 50.3 and 67.3 mL per min at 100, 200 and 300 mmHg pressure, respectively. The peak effects of atropine and adrenaline via this route were seen at approximately 1 min after injection. Resuscitation using this method was uniformly successful in all dogs via the corpus cavernosum, with all reaching or exceeding their premorbid central venous pressure (CVP), and approaching or reaching their premorbid mean arterial pressure (MAP). In comparison the control dog's CVP and MAP did not rise during the period of observation after it was bled. Conclusions: The corpus cavernosum is a practical alternative means of intravenous access in the emergency setting in the dog model. [source]

Success of Ultrasound-guided Peripheral Intravenous Access with Skin Marking

ACADEMIC EMERGENCY MEDICINE, Issue 8 2008
Jessica R. Resnick MD
Abstract Objectives:, The most effective technique for ultrasound-guided peripheral intravenous access (USGPIVA) is unknown. In the traditional short-axis technique (locate, align, puncture [LAP]), the target vessel is aligned in short axis with the center of the transducer. The needle is then directed toward the target under real-time ultrasound (US) guidance. Locate, align, mark, puncture (LAMP) requires the extra step of marking the skin at two points over the path of the vein and proceeding with direct visualization as in LAP. The difference in success between these two techniques was compared among variably experienced emergency physician and emergency nurse operators. Methods:, Subjects in an urban academic emergency department (ED) were randomized to obtain intravenous (IV) access using either LAP or LAMP after two failed blind attempts. Primary outcomes were success of the procedure and time to complete the procedure in variably experienced operators. Results:, A total of 101 patients were enrolled. There was no difference in success between LAP and LAMP, even among the least experienced operators. Of successful attempts, LAMP took longer than LAP (median 4 minutes, interquartile range [IQR] 4,10.5 vs. median 2.9 minutes, IQR 1.6,7; p = 0.004). Only the most experienced operators were associated with higher levels of success (first attempt odds ratio [OR] 6.64; 95% confidence interval [CI] = 2 to 22). Overall success with up to two attempts was 73%. Complications included a 2.8% arterial puncture rate and 12% infiltration rate. Conclusions:, LAMP did not improve success of USGPIVA in variably experienced operators. Experience was associated with higher rates of success for USGPIVA. [source]

Peripherally inserted central catheter use in the hospitalized patient: Is there a role for the hospitalist?,

JOURNAL OF HOSPITAL MEDICINE, Issue 6 2009
Adam S. Akers MD
Abstract BACKGROUND: Peripherally-inserted central venous catheters (PICCs) are frequently used in hospitals for central intravenous access. These catheters may offer advantages over traditional central catheters with respect to ease of placement and decreased complication rates. However, hospital physicians have not traditionally been trained to place PICCs. METHODS: We trained 3 of 5 hospitalists to place PICCs in our small university-affiliated community hospital as we converted from a house physician model to a hospitalist model for inpatient care. We then looked retrospectively at the rates of all PICC and other central catheter placements as well as the number of femoral and nonfemoral catheter days for the 18-month period prior to and after the inception of the hospitalist program. RESULTS: Comparing the periods prior to and after the inception of the hospitalist program, the total number of central catheter placements doubled and the PICC rate rose from 20% to 80% of all central catheters. The rate of femoral and subclavian catheter placements decreased by approximately 50% and the rate of internal jugular catheter placement was roughly unchanged. There was also a fall in the number of femoral catheter days and a great increase in the number of total nonfemoral catheter days. The rate of catheter-related bacteremia remained low and did not appear to increase. CONCLUSIONS: PICCs may be a safe and easy alternative to centrally placed catheters for the hospital physician attempting to secure central intravenous access and may lead to a decrease in the need for more risky central venous catheter (CVC) insertions.

A left paraglossal approach for oral intubation in children scheduled for bilateral orofacial cleft reconstruction surgery , a prospective observational study

PEDIATRIC ANESTHESIA, Issue 2 2009
INDU SEN MD
Summary Background:, Children with orofacial cleft defects are expected to have difficult airways. Conventional midline laryngoscopic approach of oral intubation can lead to iatrogenic tissue trauma. In this study, we evaluated the feasibility of left paraglossal laryngoscopy as a primary technique for airway management in these children. Methods:, After institutional ethical committee approval and informed consent, we enrolled 21 children with uncorrected bilateral lip and palate deformities (BL CL/P). Anesthesia was induced with halothane (0.5,4%) in 100% oxygen. After obtaining intravenous access, fentanyl 1.5 ,g·kg,1 and atracurium 0.5 mg·kg,1 were administered. Endotracheal intubation was performed with Miller's straight blade laryngoscope, introduced using left paraglossal approach. Difficulty of intubation was scored according to modified Intubation Difficulty Scale. Results:, Data consists of 21 children (15 males and six females), mean age 1.31 ± 1.18 years and weight 9.27 ± 2.57 kg. Laryngoscopic view obtained was CL II (7[33.3%]) and CL I (14[66.6%]) respectively (Figure 1). All the children could be easily intubated using left paraglossal approach, only 2/3 of them needed optimal external laryngeal manipulation to help achieving it. Though intubation could be done in the first attempt in 19 children, two infants (9½ and 11 months) required one size smaller endotracheal tube and were intubated in the second attempt using left paraglossal approach. Perioperative course was uneventful in all the children. Figure 1. ,Distribution of Intubation Difficulty scale (IDS) Score in BL CL/P patients. n (%) IDS: 0 (intubation without difficulty), IDS: 1 (slight difficulty; OELM applied/additional intubation attempt), IDS: >5 (Moderate to Major difficulty), IDS: = , (Impossible intubation). Conclusion:, Keeping in mind midline tissue support loss in cleft deformities, we propose routine use of left paraglossal laryngoscopic approach for intubating children with uncorrected BL CL/P anomalies.

Vaginal birth after Caesarean section: A survey of practice in Australia and New Zealand

AUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 3 2003

Abstract Aims: Women with a single prior Caesarean section (CS) in a subsequent pregnancy will be offered either a planned elective repeat CS or vaginal birth after Caesarean (VBAC). Recent reports of VBAC have highlighted risks of increased morbidity, including uterine rupture, and adverse infant outcome. A survey of practice was sent to fellows and members of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists to determine current care for women in a subsequent pregnancy with a single prior CS, and to assess variations by length and type of obstetric practice. Methods: Questions asked about the safety of VBAC, induction of labour with a uterine scar, and requirements to conduct VBAC and elective repeat CS. Results: A total of 1641 surveys were distributed, with 1091 (67%) returned, 844 from practicing obstetricians (51% of college membership). Almost all respondents (96%) agreed or strongly agreed that VBAC should be presented as an option to the woman, varying from 90% where the indication for primary CS was breech, 88% for fetal distress, and 55% for failure to progress. Forty percent of respondents agreed or strongly agreed that VBAC was the safest option for the woman, and associated with fewer risks than CS. In contrast, 44% of respondents disagreed or strongly disagreed that VBAC was the safest option for the infant, and opinions varied as to whether risks of VBAC outweighed those of CS for the infant. Almost two-thirds of practitioners would offer induction of labour to a woman with a prior CS in a subsequent pregnancy, one-third indicating a willingness to use vaginal prostaglandins, and 77% syntocinon. Most respondents preferred to conduct VBAC in a level two or three hospital (86%); required the availability within 30 min of an anaesthetist (81%), a neonatologist (84%), and operating theatre (97%); recommended continuous electronic fetal heart rate monitoring (86%); intravenous access (90%); and routine group and hold (79%) during labour. For an elective repeat CS, most practitioners request routine blood for group and hold (78%), a neonatologist in theatre (77%), the use of an in-dwelling urinary catheter (96%), and the use of intraoperative antibiotics (82%). Conclusions: Most obstetricians indicated VBAC to be the safest option for the woman, but were less certain about benefits and risks for the infant. The consensus of practice is to present VBAC as an option and induce labour if needed. Vaginal birth after Caesarean is preferred in a level two or three hospital, with an anaesthetist, neonatologist and operating theatre available within 30 min. The use of continuous electronic fetal heart rate monitoring and intravenous access are recommended. In planned CS, a neonatologist in theatre is preferred, and an in-dwelling urinary catheter and intraoperative antibiotics will be used. [source]

Emergency Department Management of Acute Pain Episodes in Sickle Cell Disease

ACADEMIC EMERGENCY MEDICINE, Issue 5 2007
Paula Tanabe PhD
ObjectivesTo characterize the initial management of patients with sickle cell disease and an acute pain episode, to compare these practices with the American Pain Society Guideline for the Management of Acute and Chronic Pain in Sickle-Cell Disease in the emergency department, and to identify factors associated with a delay in receiving an initial analgesic. MethodsThis was a multicenter retrospective design. Consecutive patients with an emergency department visit in 2004 for an acute pain episode related to sickle cell disease were included. Exclusion criteria included age younger than 18 years. A structured medical record review was used to abstract data, including the following outcome variables: analgesic agent and dose, route, and time to administration of initial analgesic. Additional variables included demographics, triage level, intravenous access, and study site. Mann,Whitney U test or Kruskal,Wallis test and multivariate regression were used to identify differences in time to receiving an initial analgesic between groups. ResultsThere were 612 patient visits, with 159 unique patients. Median time to administration of an initial analgesic was 90 minutes (25th to 75th interquartile range, 54,159 minutes). During 87% of visits, patients received the recommended agent (morphine or hydromorphone); 92% received the recommended dose, and 55% received the drug by the recommended route (intravenously or subcutaneously). Longer times to administration occurred in female patients (mean difference, 21 minutes; 95% confidence interval = 7 to 36 minutes; p = 0.003) and patients assigned triage level 3, 4, or 5 versus 1 or 2 (mean difference, 45 minutes; 95% confidence interval = 29 to 61 minutes; p = 0.00). Patients from study sites 1 and 2 also experienced longer delays. ConclusionsPatients with an acute painful episode related to sickle cell disease experienced significant delays to administration of an initial analgesic. [source]
