Abstract
PURPOSE To present an oral anesthesia protocol for in-office oculoplastic surgery and to compare safety outcomes and patient and physician experiences to ambulatory surgery center (ASC)-based surgery with intravenous sedation or general anesthesia. METHODS A prospective study was performed on consecutive patients undergoing surgery at an oculofacial plastic surgery practice. Surgery was performed in an in-office setting using our standardized oral sedation protocol or at an ASC with intravenous sedation or general anesthesia. Preoperative and postoperative surveys were conducted by patients and physicians to compare surgical experience, safety, and efficacy of our oral sedation protocol for in-office surgery in the ASC setting. RESULTS Two hundred and fifty-three patients (167 in-office and 86 at ASC) underwent surgery between March and November 2022. There was no significant difference in how patients or physicians rated their experience between the 2 locations. A significantly higher proportion of ASC patients would have rather had surgery in-office (34.9% vs. 19.2%; p = 0.006). A significantly higher number of physicians in the office setting would have rather performed surgery at the ASC than the reverse (12.7% vs. 2.3%, respectfully; p = 0.007). There were no safety complications reported in either setting. CONCLUSIONS Within our patient cohort, the presented oral sedation protocol provided safe and effective anesthesia for in-office oculoplastic surgery that is comparable to an ASC.

Abstract
Orbital exenteration is occasionally required for rhino-orbital cerebral mucormycosis. Multiple associated comorbidities can pose a risk for general anesthesia. There is only 1 report of exenteration being performed under trigeminal nerve block. We describe 5 patients who underwent orbital exenteration under local infiltration anesthesia with sedation. Patients and surgeons reported satisfactory conditions, with stable hemodynamics and successful day care management. Orbital exenteration under local infiltration anesthesia can be a safe and effective alternative for patients with rhino-orbital mucormycosis who are at risk with use of general anesthesia.

Abstract
Thyroid eye disease is an autoimmune inflammatory disorder of the orbit in adults. It causes inflammation, expansion and fibrosis of orbital fat, muscles and the lacrimal gland, leading to facial disfigurement, functional disability and, in severe cases, blindness. Overall, approximately 20% of affected patients need some form of surgical intervention requiring anaesthesia. This narrative review explores the background of thyroid eye disease, surgical procedures performed and their implications for anaesthesia. General anaesthesia is used for orbital decompression procedures, strabismus correction surgery and complex oculoplastic procedures. Local anaesthetic infiltration or regional anaesthesia under monitored anaesthesia care are the techniques most commonly employed for eyelid retraction surgery. It is important to limit the volume of local anaesthetic agent used during infiltration and continuously monitor the orbital volume and ocular pressure with a ballottement technique. In addition, the contralateral eye should be checked and, if necessary, protected against corneal exposure. Retrobulbar, peribulbar and sub-Tenon's blocks are best avoided. Topical anaesthesia has been used for some strabismus correction surgery but its use is limited to motivated and cooperative patients only.

Abstract
PURPOSE To evaluate the efficacy of retro-peribulbar and subconjunctival anesthesia associated with intravenous sedation in patients undergoing evisceration and orbital implant placement. METHODS The charts of 217 patients who underwent evisceration with trans-scleral implant placement were reviewed. Midazolam and fentanyl were used for intravenous sedation. For local anesthesia, a combination of lidocaine with epinephrine and bupivacaine was injected into the retrobulbar, upper peribulbar, and subconjunctival areas. The intraoperative pain and need for supplemental anesthetic injection were recorded prospectively. RESULTS The surgery was performed with local anesthesia in 116 patients (53%) and with general anesthesia in 101 patients (47%). Patients were significantly older in the local anesthesia group than in the general anesthesia group (mean age, 59.9 years vs 45.2 years; P < .05). Supplemental retrobulbar anesthesia was required in 5 patients (4.3%). Transition to general anesthesia was required in 1 patient (0.9%) due to severe anxiety. Orbital hemorrhage developed after retrobulbar injection in 1 patient (0.9%), but did not preclude performing evisceration. CONCLUSIONS Combined retro-peribulbar and subconjunctival anesthesia with intravenous sedation can provide safe and effective intraoperative analgesia for evisceration surgery with trans-scleral implant placement.

Abstract
PURPOSE To establish the efficacy of a regional nerve block of the upper eyelid and its effect on levator motor function. METHODS Forty-one patients underwent surgery on 54 upper eyelids by one surgeon, after administration of a regional nerve block at the supraorbital notch. The amount of pain experienced by patients due to the local anesthetic injection and surgery was determined by using visual analogue scores. The effect of the local anesthetic injection on levator function was determined by comparing the measured levator function prior to and following administration. Any complications attributable to the regional sensory nerve block were recorded. RESULTS Ninety-two percent of patients found the injection painless, and the rest reported negligible pain. The mean pain score for the injection was 2 (SD 1.3, range 0-6). The mean pain score for the surgery was 0.3 (SD 0.6, range 0-3). No significant difference was found in levator function prior to and following the injection (pre-function: 14.4 mm, post-function: 13.4 mm, p=0.01). One patient had hematoma formation at the site of injection. CONCLUSIONS A regional nerve block of the upper eyelid achieves effective sensory anesthesia,without compromising motor function. This helps in an accurate assessment of intraoperative height during upper lid surgery.

Abstract
We investigated operative course and post-operative findings of patients undergoing primary enucleation for uveal melanoma versus those requiring secondary enucleation after brachytherapy. A retrospective chart review was performed with IRB approval on patients receiving treatment for uveal melanoma. Patients with enucleation as initial treatment and patients enucleated after plaque brachytherapy were analyzed for demographic data, operative course, and post-enucleation outcome. Further cause analysis for secondary enucleations was investigated. No significant difference was seen in age, laterality, or gender between the primarily enucleated (n = 54) and secondarily enucleated (n = 34) groups. Greater difficulty with surgery was noted in 28/32 (87.5%) of secondary enucleations compared to 1/54 (1.8%) of primary enucleations (p < 0.0001). Operative time was >2 hours in 3/51 (6%) of primary enucleations (vs. 8 of 32, 25%, p = 0.02). Average implant size was similar in the 2 groups (20.6 mm), however 2/34 (6%) of secondary enucleations required dermis fat grafting. Post-enucleation anophthalmic ptosis occurred after 8/49 (16%) of primary cases (vs. 13/30, 43%, p = 0.02) and prosthetic enophthalmos after none (0%) of primary cases (vs. 5/30, 17%, p = 0.006). Class 2 gene expression profile was found in 6/8 (60%) of eyes enucleated for treatment failure. Secondary enucleation performed after plaque brachytherapy was technically more difficult, and had more anophthalmic socket and eyelid complications compared to primary enucleation for uveal melanoma. Primary enucleation may avoid additional surgery and morbidity in a subset of patients with contraindications to plaque brachytherapy.

Abstract
PURPOSE A number of agents have previously been reported to be safe and effective for sedation and analgesia in ophthalmic surgery under local anaesthesia, but there has been no previous patient-focused assessment of this form of conscious sedation. We present a patient satisfaction survey, including a validated pain score, for patients undergoing oculoplastic procedures under local anaesthesia with alfentanil sedation. METHODS A prospective, non-randomized, questionnaire-based study of the experience, satisfaction and pain scores of consecutive patients undergoing oculoplastic procedures under local anaesthesia with alfentanil sedation at University Hospital, Coventry, UK, under the care of one Consultant Oculoplastic Surgeon between 2006 and 2009. RESULTS Three hundred and sixty-seven patients were surveyed over the 3-year period. Overall, 52% were female and 89% of Caucasian ethnic origin. Mean duration of surgical procedures was 34 minutes (range 2-120 minutes). Over 90% of patients described a low pain score, both during the local anaesthetic injection and per-operatively, and 98% stated that they were happy to have this sedation technique for further oculoplastic surgery in future. Side effects related to sedation were reported in 5% of patients. There were no conversions to general anaesthesia and no day-case patients required an overnight in-patient stay. CONCLUSION Conscious sedation with alfentanil for oculoplastic procedures under local anaesthesia results in low pain scores and high patient satisfaction with minimal complications.

Abstract
PURPOSE To compare the level of sedation of oral administration of diazepam or midazolam associated or not with clonidine and their effects on upper eyelid margin position, heart rate, arterial pressure, and oxygen saturation. METHODS Seventy consecutive healthy patients American Society of Anesthesiologists (ASA) grade I-II scheduled for lower eyelid blepharoplasty were randomized into 4 groups according to the oral sedative agent used (group 1, diazepam 10 mg; group 2, diazepam 10 mg plus clonidine 0.15 mg; group 3, midazolam 15 mg; group 4, midazolam plus clonidine 0.15 mg). For all patients, the midpupil-to-upper eyelid margin distance, the heart rate, systolic and diastolic blood pressure, and oxygen saturation were recorded before and 1 hour after the administration of oral medication. The level of sedation at the time of surgery was measured with the Michigan University scale. RESULTS The depth of sedation was significantly more pronounced with midazolam (median score = 2) than with diazepam (median score = 1). Clonidine slightly increased the level of sedation of both diazepam and midazolam. The diastolic arterial blood pressure drop with midazolam associated or not with clonidine was significantly greater than with diazepam. The mean upper eyelid margin position shift (-1.42 mm) verified when clonidine was associated with midazolam was also significantly greater than with diazepam. DISCUSSION Oral sedation with diazepam or midazolam associated or not with clonidine is safe for ASA grade I-II patients. The systemic effects of diazepam and midazolam were small and very similar. The sedation induced by midazolam was clearly greater than that induced by diazepam. However, this higher level of sedation was accompanied by a more important shift in upper eyelid margin position.

Abstract
Office-based anesthesia (OBA) is a unique and challenging venue, and, although the clinical outcomes have not been evaluated extensively, existing data indicate a need for increased regulation and additional education. Outcomes in OBA can be improved by education not only of anesthesiologists but also of surgeons, proceduralists, and nursing staff. Legislators must be educated so that appropriate regulations are instituted governing the practice of office-based surgery and the lay public must be educated to make wise, informed decisions about choice of surgery location. The leadership of societies, along with support from the membership, must play a key role in this educational process; only then can OBA become as safe as the anesthesia care in traditional venues.

Abstract
PURPOSE To compare the morbidity of general anesthesia versus periocular anesthesia with monitored intravenous sedation for enucleation of the eye. METHODS A retrospective study of 39 patients who underwent enucleation. RESULTS For anesthesia during enucleation, 21 patients received periocular anesthesia with monitored intravenous sedation and 18 patients received general anesthesia. During recovery on the day of surgery, 94% (17/18) of general anesthesia patients required postoperative analgesics, compared with 52% (11/21) of periocular anesthesia with monitored intravenous sedation patients (p = 0.0046). Postoperative antiemetic treatment of nausea and vomiting on the day of surgery was required in 56% (10/18) of general anesthesia patients, but only 5% (1/21) of periocular anesthesia with monitored intravenous sedation patients (p = 0.0008). On contacting these patients, no patients receiving periocular anesthesia with monitored intravenous sedation had a negative memory of the surgery and all but 2 indicated they would elect the same type of anesthesia in retrospect. Periocular anesthesia with monitored intravenous sedation related costs were substantially less than those associated with general anesthesia. CONCLUSIONS Periocular anesthesia with monitored intravenous sedation for enucleation reduces early postoperative morbidity and is more cost effective than general anesthesia. It is an anesthetic alternative that should be considered for patients undergoing enucleation of the eye.

Abstract
BACKGROUND Blepharoplasty can be performed in the office setting using oral medication with the patient under local anesthesia. This article reviews the authors' experience with this approach, evaluating patient satisfaction and demonstrating why this technique has become their procedure of choice for selected healthy patients. METHODS The authors conducted a retrospective review of the 86 patients who underwent office-based blepharoplasty and mailed surveys to assess patient satisfaction with the procedure. RESULTS Upper and lower blepharoplasties were performed with no major complications. The surveys were completed and returned by 83% of the patients. The survey results indicated that this procedure is well accepted and highly rated by patients. Many patients unwilling to undergo blepharoplasty outside the office were willing to have the procedure using this approach. A strong majority indicated that they would be referring friends and family for the procedure. CONCLUSIONS The fact that blepharoplasty can be performed in the office using oral medication with the patient under local anesthesia proves to be a strong determinant toward the final decision of patients to undergo surgery. This procedure meets the safety requirements outlined by the American Society of Plastic Surgeons (ASPS) and is desired by our patients for its many obvious advantages. Recommendations are provided to assist others who desire to use this safe and cost-effective method.

Abstract
PURPOSE To evaluate patient comfort with outpatient orbital surgery. DESIGN Prospective, non-randomized study. METHODS The experience of 34 consecutive outpatient orbital procedures in 30 patients was evaluated. The data obtained included subjective postoperative pain and discomfort at 3 time intervals (immediate, postoperative day 1 and 1 week) using a 100 mm visual analogue scale (VAS). Patients were also asked to rate the overall experience after one week of follow-up. RESULTS The average pain and discomfort scores in the immediate postoperative period measured 13.95 and 12.61, respectively. Overnight scores of 5.91 and 7.25 were determined for pain and discomfort, and at the one-week follow-up these were 0.91 and 3.42, respectively. All 30 patients reported that they were "satisfied with their overall experience." The highest VAS score for pain at any time was 50. The highest VAS score for discomfort at any time was also 50. All 30 patients had recovered or improved their visual acuity at week one. There was no incidence of retrobulbar hemorrhage, significant loss of vision (greater than two lines), increased intraocular pressure or pupillary defects in any of the patients. None of the study patients required re-hospitalization. CONCLUSIONS This study suggests that outpatient orbital surgery, in the hands of an experienced orbital surgeon, is safe and well tolerated by the patients regardless of the type of anesthesia or type of procedure.

Abstract
BACKGROUND The purpose of the study is to compare characteristics of Aboriginal patient hospital admissions with non-Aboriginal admissions to the Ophthalmology Unit of the Royal Adelaide Hospital. METHODS A retrospective review of separation data was undertaken of hospital inpatient and day surgery admissions to the Royal Adelaide Hospital Ophthalmology Unit for the period July 1997 to January 2005. RESULTS There were 11 944 admissions to the Ophthalmology Unit (including inpatients and day surgery cases), of which 273 (2.29%) were Aboriginal patients. Of the total, 2779 (23.3%) patients were admitted for at least 24 h (inpatients), and 9165 (76.7%) stayed less than 24 h (mostly day surgery cases). Aboriginal patients comprised 6.8% of inpatient admissions, and 0.9% of admissions less than 24 h. The average age of Aboriginal patients (52.9 years) was significantly less than non-Aboriginal patients (62.6 years; P < 0.0001). The median length of stay for Aboriginal patients was 5 days compared with 3 days in non-Aboriginal patients. Aboriginal patients were more likely to be from interstate (RR 10.3 P < 0.0001), more likely to have diabetes mellitus (RR 2.7 P < 0.0001), and more likely to be admitted for cataract surgery (RR 4.18 P < 0.0001) and lid disorders (RR 6.04 P < 0.0001) than non-Aboriginal patients. CONCLUSION Aboriginal patients admitted to the Ophthalmology Unit were younger in age, more frequently from interstate, and had longer admissions than non-Aboriginal patients. These results have important implications for ophthalmic health-care planning.

Abstract
BACKGROUND AND OBJECTIVE The implication of intrathecal lidocaine in neurological toxicity has made intrathecal bupivacaine the commonly used drug for local anaesthesia in ambulatory surgery. However, in high doses intrathecal bupivacaine may produce a high level of sensory and motor block, and arterial hypotension; discharge from hospital may be delayed. Intrathecal opioids added to low-dose local anaesthetics produce a synergistic effect without increasing the sympathetic block or delaying discharge. The aim of our study was to identify the minimum effective dose of intrathecal fentanyl that in combination with low-dose intrathecal bupivacaine would provide adequate surgical conditions without prolonging recovery. METHODS A prospective, single, blind, randomized study was conducted in 45 adult males scheduled for minor urological procedures using intrathecal anaesthesia on a day care basis. Patients were randomly assigned to one of three groups (n = 15 each). They received bupivacaine 0.17% 5 mg--with either fentanyl 7.5 microg (fenta-7.5), 10 microg (fenta-10) or 12.5 microg (fenta-12.5) intrathecally in a total volume of 3 mL. The quality of anaesthesia, haemodynamic stability, time to two-segment and S2 regression, time to micturition, and time to discharge were assessed. RESULTS The time to two-segment regression and S2 regression with fenta-12.5 was significantly longer than with fenta-7.5 and fenta-10 (P < 0.01). Fenta-7.5 had a significantly higher number of failed blocks (four patients) compared with fenta-12.5 (P < 0.05). The time out of bed, time to micturition and time to discharge were significantly longer with fenta-10 and fenta-12.5 compared with fenta-7.5, and also with fenta-12.5 compared with fenta-10 (P < 0.01). Haemodynamic stability did not differ for all the drug combinations. CONCLUSIONS Fentanyl 12.5 microg added to low-dose bupivacaine (5 mg) intrathecally provides better surgical anaesthesia and increased reliability of block than intrathecal fentanyl 7.5 or 10 microg. Haemodynamic stability was the same for all dose combinations used.

Abstract
The aim of this Review is to introduce anaesthesiologists to the basic physical principles that are important for their work. A better understanding of the underlying processes during anaesthesia is required for greater safety and efficiency. Relevant physical quantities are presented along with the area of anaesthesiology where they are used. This approach provides better targeting to the needs of practising anaesthesiologists. This text has been a part of a specialist course in anaesthesiology at the University of Ljubljana for some years. Current results show that both the students and the specialist anaesthesiologists now show a better understanding of the underlying physical principles required for their work and are more successful in fulfilling the needs of their practical work.

Abstract
BACKGROUND AND OBJECTIVE Benzodiazepines may cause hypotension and are reported to interfere with smooth vascular muscle activity. The aim was to elucidate the influence of three different benzodiazepines on the vascular reactivity of coronary arteries. METHODS Using the model of isolated vessels, we studied the impact of midazolam (0.15, 1.5, 15 microg mL(-1)), diazepam (0.1, 1.0, 10 microg mL(-1)) and flunitrazepam (0.01, 0.1, 1.0 microg mL(-1)) on the contractile responses to histamine (2 x 10(-5) mol L(-1)) and serotonin (3 x 10(-5) mol L(-1)) in isolated intact and denuded coronary arteries. RESULTS Midazolam significantly attenuated the contractile response when administered in high concentrations (15 microg mL(-1)). This effect was more pronounced in intact than in denuded preparations (histamine: -22.7 versus -7.3%, P = 0.0079; serotonin: -47.1 versus -15.9%, P < 0.0001). Diazepam and flunitrazepam exerted no significant effects on the vascular tone of coronary arteries. CONCLUSIONS Midazolam, but not diazepam or flunitrazepam, attenuates the contractile responses to vasoconstrictors in concentrations beyond those used in clinical practice. This effect is in part mediated by endothelial factors.

Abstract
BACKGROUND AND OBJECTIVE In October 2000, we conducted a national postal survey of consultant day case anaesthetists in the UK to explore the range and variation in the practice of anaesthetizing a patient for day case surgery (paediatrics, urology and orthopaedics). The survey was carried out as part of a larger study that comprised a major two-centre randomized controlled trial designed to investigate the costs and outcome of several anaesthetic techniques during day care surgery in paediatric and adult patients (cost-effectiveness study of anaesthesia in day case surgery). We report the findings of this national survey of adult urology and orthopaedic day case anaesthetic practice in the UK. METHODS The survey used a structured postal questionnaire and collected data on the duration of the surgical procedure; the use of premedication; the anaesthetic agents used for induction and maintenance; the fresh gas flows used for anaesthesia; the use of antiemetics; and the administration of local anaesthesia and analgesia. RESULTS The overall response rate for the survey was 74% (63% for urology, 67% for orthopaedics). The survey indicated the following practice in adult urology and adult orthopaedic day case surgery: 6 and 12% used premedication; propofol was the preferred induction agent (96 and 97%) and isoflurane the preferred maintenance agent (56 and 58%); 32 and 41% used prophylactic antiemetics; 86 and 93% used a laryngeal mask. CONCLUSIONS This survey identifies the variation in current clinical practice in adult day surgery anaesthesia in the UK and discusses this variation in the context of current published evidence.

Abstract
BACKGROUND AND OBJECTIVE It has been suggested that dexamethasone potentiates the sensory block produced by bupivacaine when both drugs are loaded in microspheres. The aim of the study was to evaluate the effect of dexamethasone on the brachial plexus block obtained with plain bupivacaine and bupivacaine-loaded microspheres. METHODS Dexamethasone alone (Group 5) or added to plain bupivacaine (75 mg) with (Groups 3 and 4) and without pH correction (Group 2) was compared with plain bupivacaine (75 mg; Group 1). The effect of a small dose of dexamethasone (0.42 mg) was then evaluated on the brachial plexus block obtained with bupivacaine (750 mg) as bupivacaine-loaded microspheres (Group 6). Dexamethasone was added either in the suspending medium (Group 7) or incorporated with bupivacaine into microspheres (Group 8). The motor block was evaluated in a plexus brachial sheep model. RESULTS Dexamethasone alone did not produce any motor block. When added to plain bupivacaine without pH correction, complete motor block could not be obtained. When the pH was corrected, addition of dexamethasone to plain bupivacaine seemed to delay the onset of motor block and did not prolong its duration, and it had no effect on the pharmacokinetics of bupivacaine. With bupivacaine-loaded microspheres, the duration of complete motor block was reduced when a small dose of dexamethasone was added in the suspending medium. However, the duration of motor block was significantly prolonged when dexamethasone was incorporated with bupivacaine into microspheres. CONCLUSIONS Despite the delayed onset of motor block, the incorporation of dexamethasone in bupivacaine-loaded microspheres dramatically increases the duration of action (700 +/- 485-5160 +/- 2136 min), which could be clinically relevant when such a drug-delivery system will be available.

Abstract
BACKGROUND AND OBJECTIVE The aim was to study the rapid changes in cardiac output and systemic vascular resistance produced by intravenous epinephrine (5 microg) on a beat-by-beat basis. METHODS Ten patients were studied during cardiac surgery. Radial or brachial arterial pressure was recorded continuously during intravenous administration of epinephrine (5 microg). Cardiac output and systemic vascular resistance were derived for each beat using arterial pulse contour analysis calibrated by lithium indicator dilution. In each patient a further dose of epinephrine (5 microg) was administered during cardiopulmonary bypass with the blood flow kept constant so that changes in arterial pressure corresponded to changes in systemic vascular resistance. RESULTS When the patients were not on cardiopulmonary bypass, the epinephrine produced an initial increase in systemic vascular resistance to 129 +/- 15% (mean +/- SD) of control, followed by a more prolonged reduction to 57 +/- 13% of control. Cardiac output showed a small initial reduction coincident with the increase in systemic vascular resistance, followed by an increase to 152 +/- 24% of control. During cardiopulmonary bypass, the changes produced by epinephrine on systemic vascular resistance were qualitatively similar but smaller in amplitude, probably because of a greater volume of dilution in the bypass circuit. CONCLUSIONS Small bolus doses of epinephrine produce an initial increase in systemic vascular resistance followed by a much greater reduction that may cause hypotension.

RESULTS The overall response rate for the survey was 74 and 63% for the paediatric section of the survey. Respondents indicated that 19% used premedication, 63% used propofol for induction, 54% used isoflurane for maintenance, 24% used prophylactic antiemetics and 85%, used a laryngeal mask. The findings of this national survey are discussed and compared with published evidence.

Abstract
BACKGROUND AND OBJECTIVE We ascertained whether dreams during short general anaesthesia influence subsequent patient satisfaction and anxiety. METHODS Fifty female patients were randomized into two groups to test for a difference between intravenous and inhalational anaesthesias. In Group Propo, anaesthesia was induced and maintained with propofol; in Group Metho-Iso, anaesthesia was induced with methohexital and maintained with isoflurane. Satisfaction and anxiety with anaesthesia were evaluated using a visual analogue scale from 0 to 100. Dream incidence rate, satisfaction and anxiety were assessed from immediately after waking until 3 months later. RESULTS Seventeen patients (34%) dreamed during anaesthesia. There were no significant differences in satisfaction or anxiety after anaesthesia between the dreaming and non-dreaming patients (satisfaction, 92.3 +/- 21.6 versus 92.1 +/- 21.6; anxiety, 21.1 +/- 21.1 versus 30.3 +/- 32.1), or between Group Propo and Group Metho-Iso (satisfaction, 94.4 +/- 19.3 versus 90.0 +/- 23.4; anxiety, 26.0 +/- 27.6 versus 28.4 +/- 30.7). There was no significant difference in the incidence rate of dreaming with the type of anaesthesia used (Group Propo, 11 patients; Group Metho-Iso, 6 patients). CONCLUSIONS Dreaming during general anaesthesia is common but does not influence satisfaction or anxiety after anaesthesia.

Abstract
PURPOSE To evaluate the safety and efficacy of using a telephone call within 24 hours as the initial follow-up after outpatient ophthalmic plastic surgery, deferring the first postoperative visit 4 to 7 days. METHODS We prospectively evaluated clinical outcomes, including complications and patient satisfaction, after 469 outpatient eyelid, lacrimal and anterior orbital procedures. Patient satisfaction was assessed with a 13-item questionnaire. RESULTS Response to the questionnaire was 282 of 469 (60%) patients. Essentially, all patients responding to the questionnaire who received a telephone call believed that it was helpful and their questions and concerned were adequately addressed. Only 4 of 274 (1%) patients without a planned 24-hour visit indicated that they would have preferred being seen in the office. Complications of a minor nature were noted in 12 of 469 (3%) patients, none of which adversely affected clinical outcomes. CONCLUSION We conclude that a telephone call on the initial postoperative day, deferring the first visit 4 to 7 days, is a safe, cost-effective strategy with high patient acceptance for most types of eyelid and lacrimal surgery, as well as some types of orbital surgery.

Abstract
PURPOSE Oculoplastic surgery with infiltration of local anaesthesia at the operative site performed as a day-case procedure is both efficient and cost-effective. Patients considered unsuitable for this because of fear or apprehension may, however, benefit from per-operative conscious sedation. We sought to study the efficacy and safety of this using midazolam, a water-soluble benzodiazepine. METHOD We have performed a controlled clinical trial comparing the effect of a low-dose intravenous infusion of midazolam (0.2 mg/ml of normal saline at a rate of 1 mg/h) with saline placebo on 48 subjects undergoing oculoplastic surgery with local anaesthesia. Patients were given pre- and post-operative questionnaires assessing, amongst other factors, anxiety levels, pain, degree of reported amnesia and psychomotor recovery. RESULTS Using the low-dose midazolam infusion no adverse cardiorespiratory reactions occurred. Patients receiving midazolam reported remembering significantly less about their operation than controls (p = 0.04) and showed significantly lower state-anxiety after their operation than before (p < 0.02). This change was not noted in the placebo group. There was no significant difference in the psychomotor performance of patients given midazolam compared with controls 2 h after surgery. CONCLUSIONS A low-dose continuous infusion of midazolam can be used to safely provide effective anxiolysis and conscious sedation with good psychomotor recovery during oculoplastic procedures in a day-case setting.
