[Ethyl chloride]. / Cloruro de etilo.

The control of symptoms in general and pain in particular, remains a current topic in scientific conferences and meetings, and discussed the recommendations of the Scientific Societies. Do not suffer unnecessary pain because the treatment is a right of every patient and facilitating action to control it, by nurses, is an expression of respect for that right. A common procedure nursing care consists of venous and arterial puncture for blood samples or to place catheters for different purposes, these procedures are painful for the patient and sometimes unpleasant by the need to perform them repeatedly. There are different relaxation techniques that can help to reduce this effect in the body but also have pharmacological interventions to help decrease the pain associated with vascular punctures. One of them, easy to use, quick to act and no side effects is the use of topical anesthesia by cold ethyl chloride.

The effect of needle bevel position on pain for subcutaneous lidocaine injection.

It is a common practice for medical practitioners to use subcutaneous infiltration of lidocaine to alleviate the pain of intravenous cannulation or line insertion. Although previous studies have assessed several factors affecting the pain associated with local anesthetic infiltration, there is a paucity of data on the effects of needle bevel position. In this prospective, randomized, controlled trial, we compared the effect of two different needle bevel positions (bevel up versus bevel down) and the pain associated with the subcutaneous injection of 1% lidocaine in 50 adult volunteers. Significantly higher pain scores were observed when the needle was placed bevel down compared with bevel up (P = .02). No significant differences in pain scores were noted between the groups for age and gender.

An evaluation of the administration of sub-Tenon local anaesthesia by a nurse practitioner.

AIM: To evaluate the administration of sub-Tenon local anaesthesia (LA) by a nurse practitioner. METHODS: 106 consecutive patients listed for cataract surgery were given sub-Tenon's anaesthesia by a nurse practitioner. The surgical procedure was performed within 15 minutes of the administration of the LA. Pain, state and adequacy of anaesthesia, appearance of the eye, and patient anxiety were measured. Patients' experiences of this new nursing role were gained through interview. RESULTS: At the beginning of surgery, few patients showed eye movement in any of the four quadrants and the surgeons reported that akinesia was inadequate in only seven (7.1%) cases. Three patients (3.3%) gave a pain score of 3 out of 10 or above during surgery whereas the surgeons assessed the pain relief to be inadequate in eight (8.1%) cases. Five (5.3%) patients required a top up of anaesthesia and 51 (39.8%) patients developed conjunctival chemosis in two or more quadrants. Overall, patients' comments indicate that they were pleased with the new service. CONCLUSION: The results suggest that nurse practitioner delivered sub-Tenon LA is an effective and safe method of LA administration for cataract surgery.

Comparing two methods of topical anesthesia used before intravenous cannulation in pediatric patients.

INTRODUCTION: The purpose of this study was to compare the efficacy of two methods of topical anesthesia before venipuncture or intravenous cannulation of pediatric patients to assess which type of topical anesthetic would better alleviate pain in the least amount of time with the greatest success rate of cannulation. METHODS: This study was a randomly controlled trial of 100 preoperative pediatric patients aged 5 to 21 years. The following methods of topical anesthesia were compared: (a) iontophoresis of a topical solution of 2% lidocaine with epinephrine 1:100,000 using a Phoresor Dose Controller (PDC) with Numby Stuff electrodes and a eutectic mixture of local anesthetic and (b) 2.5% lidocaine and 2.5% prilocaine (eutectic mixture of local anesthetics [EMLA] cream). RESULTS: Children reported less pain with iontophoresis (M = 0.08) compared with EMLA cream (M = 1.88, P < .001). Time to accomplish topical anesthesia was shorter with iontophoresis (13 minutes) compared with EMLA cream (60 minutes, P < .001). Failure to accomplish venipuncture occurred 5 times with the iontophoresis method and 8 times with the EMLA method (not significant). No dermal burns resulted from use of iontophoresis. DISCUSSION: We conclude that use of iontophoresis in pediatric patients is safe, rapid, and significantly more effective than is EMLA cream in reducing pain associated with venipuncture or intravenous cannulation.

Topical anaesthesia before suturing children's minor lacerations: a critical review.

This paper will critically review all the research carried out over the past 18 years concerning the use of topical anaesthetics for anaesthetizing wounds prior to closure. The review follows guidelines set out by Pollit and Hungler (1995) and Avis (1994) for critiquing research studies, and concentrates on the literature search, research objectives and design, data collection methods, sampling and data analysis.

The use of topical anaesthesia at children's minor lacerations: an experimental study.

BACKGROUND: In a great many situations within health care and treatment, children are subjected to unnecessary pain and suffering. When local anaesthetics is to be administered the child can experience this as incomprehensible especially when the nursing staff assures the child that no pain would be felt, only to discover soon after, that it actually did hurt at the moment of anaesthetic infiltration. The soothing of pain during the suturing of wounds in emergency wards can be reduced, ensuring that unnecessary pain in the cafe-and-treatment process is mot meted out to children. In order to prevent this (subjection to unnecessary pain), and by improving accepted practice, it was interesting to investigate whether children felt pain at the time of infiltration anaesthesia following the initial topical anaesthesia. AIM: The aim of the present study was to investigate the effects of introductory topical anaesthesia using Xylocain solution dropped in the wound prior to a definitive infiltration-anaesthesia. An experimental, prospective design was used where children were included in either an experimental group or a control group. The experimental group (n=10) were given a Xylocain solution while the control group (n=10) received physiological Sodium solution. Data collection for the study was made by making VAS estimates and by interviews. RESULT: The study shows that a certain alleviation of pain does occur when using Xylocain but no statistically significant difference exists between the two groups. Irrespective of whether the children received an introductory topical anaesthesia with Xylocain or Sodium solution at the time of infiltration anaesthesia, they expressed pain in connection with infiltration. The study also shows that many children express fear and anxiety. CONCLUSION: Current research highlights the difficulties involved in offering children a really satisfactory form of pain relief in connection with infiltration anaesthesia and suturing of wounds. It is urgent to throw more light on children's pain, both from a nursing and from a medical point of view. No statistically significant difference was found in children's reported pain, after treatment with Xylocain but the solution can have a positive effect at the time of the infiltration jab, but a larger study needs to be done in order to establish this firmly.

The advantages and disadvantages of Bier's blocks and haematoma blocks for Colles' fractures in A&E.

In the author's current area of practice the use of either the Bier's block or haematoma block for manipulating distal radial fractures seems to have been based mostly on the A&E consultant's preference. The purpose of this literature review was to determine if there was sufficient evidence on the advantages and disadvantages of each method of regional anaesthesia to advocate the general use of one and the exclusion of the other. When reviewing the literature the author specifically looked in to three key areas to answer this question: 1) the patient's perception of pain experienced during and after the manipulation; 2) patient safety i.e. the documented risks of the anaesthetic type used; and 3) the success of the manipulation as determined by repeat radiographs immediately after the application of a plaster of Paris cast.

Pulse oximetry. Monitoring arterial hemoglobin oxygen saturation.

The pulse oximeter gives the nurse in the operating room the ability to provide optimum care for the patient having local anesthesia. With the use of this new monitoring device, the nurse can intervene with oxygen therapy before a hypoxic episode occurs.

Phacoemulsification procedures performed with topical anesthesia.

Phacoemulsification procedures with topical anesthesia, performed with small corneal incisions and 4% lidocaine hydrochloride methylparaben-free eye drops, have very high patient satisfaction rates because patients do not experience intraoperative pain, do not require sutures or eye patches, and have immediate improvements in their vision. Phacoemulsification procedures with topical anesthesia are cost-effective for surgery departments because patients have shorter hospitalizations and require fewer chargeable items. The perioperative nursing role is essential to the success of phacoemulsification procedures with topical anesthesia.

Local and regional anesthesia. Nursing implications.

Local and regional anesthesia offers many advantages and is relatively safe, resulting primarily in positive outcomes for the patient. The potential for complications and the need for patient education, however, dictate that the PACU nurse prepare the patient appropriately, remain vigilant, and initiate the necessary measures for monitoring and intervention when caring for such patients in both the preanesthesia and postanesthesia phases. Local and regional anesthetic agents and techniques have been discussed along with their implications for nursing care. Readers are also encouraged to consult the references and their own institutional policies for additional information.

An investigation of the effect of 2 sedation regimens on patient mood state following upper extremity surgery using local anesthesia.

Sedation techniques for patients undergoing minor outpatient surgery frequently include a variety of intravenous agents. The present study was designed to look for differential effects of 2 different sedation regimens on perioperative mood states. Twenty-two patients undergoing upper extremity surgery using local anesthesia were randomized to receive either propofol or midazolam intravenously for intraoperative sedation. Subjects were asked to complete a Profile of Mood States survey before and after surgery. The results of this survey were examined for differences in mood between the 2 groups that may be attributable to differences in drug effect. No significant differences were identified between propofol or midazolam regarding their effect on patient mood. Patients in both groups experienced a reduction in perioperative anxiety.

Pharmacological techniques for managing acute pain in emergency departments.

Pain is a common reason to attend hospital but it is often inadequately managed. This article examines the physiology of pain and suggests the most effective pharmacological techniques to control it.

[Effects of hand massage and hand holding on the anxiety in patients with local infiltration anesthesia].

PURPOSE: This study was to examine the effects of hand massage and hand holding as nursing interventions on the anxiety in patients with local infiltration anesthesia. METHOD: The design of this study was a nonequivalent, control group, non- synchronized design. The subjects of this study consisted of 15 patients for the hand group, 15 patients for the hand holding group and 17 patients for the control group awaiting surgery in the operation room of a general hospital in Daegu. As an experimental treatment, hand massage was carried out by the Hand Massage Protocol developed by Snyder (1995) and interpreted by Cho (1998) and hand holding developed by Cho (1998). The data were analyzed by SPSS/WIN, T-test, ANOVA, Cronbach's alpha, and the Scheffe test. RESULTS: The hand massage group and hand holding group were more effective than the control group in reducing anxiety, VAS score, systolic blood pressure and pulse rate. CONCLUSION: Hand massage and hand holding are effective nursing interventions that alleviates the psychological and physiological anxiety of patients with local infiltration anesthesia. In particular, the simple contact of hand holding is regarded as an effective and easily accessible nursing intervention in the operating room.

Vitreoretinal surgical pain.

The surgical eye nurse found that some patients undergoing vitreoretinal surgery experienced pain after the administration of local anesthesia. This study proposed to determine which local anesthesia technique provides the best comfort level for these patients. A quasi-experimental design, with a convenience sample of 41 patients and a 0-10 visual analog pain scale, was used to test the hypothesis. The findings did support the hypothesis that one particular local anesthesia technique was more significant than the others. However, this study also found that if the conjunctiva is sufficiently anaesthetized with 2% lidocaine jelly, patients experience no pain.

Local anaesthetic techniques in ophthalmic surgery.

This article, which won third place in the Alison Bell Writer's Award this year, reports the findings of a literature review that explored the use of local anaesthetic techniques used in ophthalmic surgery. The author describes the various ophthalmic procedures that can take place under local anaesthetic and asks whether there is a need for an anaesthetist to be present for such lists. Issues such as patient monitoring requirements and intravenous access are also discussed, emphasising the importance of the nurse's role in informing, supporting and comforting the patient through what can be a stressful experience.

The effectiveness of superficial subcutaneous lidocaine administration prior to femoral artery sheath removal.

The dynamic world of healthcare requires continuous review of practice to ensure that patient care aligns with current evidence and best practice. Superficial subcutaneous lidocaine injection has been an order option at London Health Sciences Centre-University Hospital (LHSC-UH) for use in post-percutaneous coronary intervention (PCI) prior to femoral artery sheath removal (FASR). The purpose of administering lidocaine is to reduce pain during FASR, subsequently enhancing the patient's experience. A critical appraisal was performed by the Continuous Quality Improvement-Cardiac Care Council (CQI-CCC) at LHSC-UH, evaluating the effectiveness of superficial subcutaneous lidocaine for use in patients undergoing FASR. This paper details the process followed to evaluate this practice and reports on the subsequent findings and recommendations. A literature review, a retrospective chart audit, a blinded online survey and peer hospital polling were compiled, and a summary of findings was shared with the cardiac interventionists, with subsequent polling. No significant evidence for pain reduction was identified when lidocaine injections were administered prior to FASR. As such, a unanimous decision was reached to remove lidocaine from the LHSC Coronary Angioplasty Clinical Pathway order form.
